How to look at the resistance value of adjustable resistor?   An adjustable resistor is a component that can control the current in a circuit by adjusting the value of the resistor. In electronic circuit design and experimentation, it is very important to adjust the resistance value correctly, as it directly affects the performance and stability of the circuit. So, what should we think about the resistance of an adjustable resistor?   The resistance value of an adjustable resistor can be viewed in the following ways: Direct Labeling: On the surface of the adjustable resistor, the resistance value is directly marked, e.g. "500 Ω" or "500 ohms". If the resistance value is not directly marked, there is usually a mark, such as a color dot or ribbon, representing a different resistance range. For example, black for 0Ω, brown for 1Ω, red for 2Ω, and so on.   Color scale method: On the surface of the adjustable resistor, different colored bands or dots are used to mark the resistance value and allowable deviation. Most of the resistors in the world use the color code method. For example, when the resistor is four-ring, the last ring is usually gold or silver, representing a deviation of ±5% or ±10%, with the first three digits being significant figures and the number of powers. When the resistance is five rings, the distance between the last ring and the first four rings is larger, the first three digits are significant figures, the fourth digit is the number of power, and the fifth digit is the deviation.   Numeric method: On adjustable resistors, a three-digit number may be used to represent the nominal value. The numbers are from left to right, the first and second digits are the valid values, and the third digits are the exponents, that is, the number of zeros, and the unit is European. Deviations are usually represented by literal symbols.   Literal symbolic method: A combination of Arabic numerals and literal symbols is used to represent the nominal resistance, and its allowable deviation is also represented by literal symbols. The number before the symbol indicates the integer resistance, and the following numbers represent the first decimal resistance and then the second decimal resistance. For example, DFGJKM stands for different allowable deviations, which are ±0.5%, ±1%, ±2%, ±5%, ±10%, ±20%, respectively.   If you need to measure the resistance value of an adjustable resistor, you can use a multimeter or a digital resistance meter to test it. The resistance value can be measured by connecting the two ends of the adjustable resistor to take a reading. By reasonably selecting and adjusting the resistance of the adjustable resistor, the current in the circuit can be better controlled, and the stable operation and performance optimization of the circuit can be realized.

The definition of potentiometer output line and the wiring method for external potentiometer speed control are as follows: Definition of potentiometer output line: Potentiometers typically have three pins, known as terminal 1 (terminal 1), terminal 2 (terminal 2), and terminal 3 (terminal 3). Among them, there is a fixed resistor connected between terminal 1 and terminal 2, and a sliding contact connected between terminal 3 and terminal 2. When the potentiometer knob rotates, the sliding contact moves on the fixed resistor, thereby changing the resistance value between terminals 1, 2, and 3. Wiring method for external potentiometer speed control: 1. Connect terminal 1 (terminal 1) of the potentiometer to the positive pole of the power supply, terminal 3 (terminal 3) to one end of the load (such as the motor), and terminal 2 (terminal 2) to the other end of the load. In this way, the potentiometer can adjust the working state of the load and achieve speed regulation function by changing the resistance value between terminals 1, 2, and 3. 2. If it is necessary to adjust the resistance of the potentiometer to achieve speed regulation function, please pay attention to keeping the voltage between terminals 1 and 3 unchanged during the adjustment process. This can ensure that the adjustment process does not affect other parts of the circuit. In practical applications, different types of potentiometers can be selected according to specific needs, such as linear potentiometers, exponential potentiometers, etc. Different types of potentiometers have different resistance variation characteristics and can be selected according to actual needs. 4. When wiring, please ensure that the rated power and withstand voltage level of the potentiometer meet the requirements of the circuit to ensure the stability and safety of the circuit.

It is normal for the potentiometer to become cold and its damping to increase. This is because the damping characteristics of the potentiometer are temperature dependent, and when the ambient temperature decreases, the resistance value of the potentiometer may increase accordingly. This phenomenon is mainly affected by the temperature coefficient of the internal material of the potentiometer. The reason for the increased damping of the potentiometer is that as the temperature decreases, the resistance of the conductive material inside the potentiometer increases, leading to a decrease in the current in the circuit, thereby increasing the damping characteristics. This phenomenon may have an impact on the normal operation of equipment in some applications that are sensitive to temperature changes. Therefore, in these applications, some measures may need to be taken to stabilize the performance of the potentiometer, such as selecting materials with better temperature stability or using temperature compensation circuits. It should be noted that different types of potentiometers may have different temperature coefficients, so when selecting a potentiometer, the appropriate one should be selected based on the specific application environment and requirements. Meanwhile, in order to ensure the normal operation of the potentiometer, it is also necessary to avoid placing it in extreme temperature environments

What is a Potentiometer? A potentiometer is a type of variable resistor. These passive components are designed to control electrical resistance, measured in Ohms (Ω). Multiple different variations are available, including trimmer and rotary potentiometers, but the functional principle remains the same. Potentiometers work by picking up an input Voltage and transferring different amounts to a circuit. This amount is determined by the position of the wiper (sometimes also known as a slide) on a resistive track. This explanation briefly describes how potentiometers can be used as voltage regulators, but they can also be used to introduce different levels of resistance, to compare the electromotive force (EMF) of two cells, or to regulate the power in a circuit. In the latter case, it is a rheostat. A typical example of a potentiometer application is the volume control on radio and stereo systems. Some still have analogue rotary potentiometers installed and despite increasing digitalisation, potentiometers are often used in electronics like these. Potentiometers may also be referred to as pots or potmeters. Potentiometer Uses Potentiometers are often used in various devices, in both industrial and consumer applications. Some common uses of potentiometers include: Mechanical rotary encoders for simple speed adjustment Comparing the EMF of a standard cell and a battery cell Controlling the electrical properties of various devices such as oscillators Volume control in audio equipment Balancing or readjusting the resistance value to avoid undesirable changes It should be noted that potentiometers can do more than just regulate resistance. For instance, they can be used as polarity converters. In this application, it is connected to two different direct current sources. The positive and negative terminals are connected on one side of the potentiometer in the + / - pattern, and the opposite on the other side. This means that the zero point is exactly in the middle. One use for this functionality is in the balance controls of audio systems. Pots are also ideal for use with adjustment devices that require highly precise resistance values. How Does a Potentiometer Work? Potentiometers essentially consist of three main components - a resistive element, the wiper, and three terminals. Two of the terminals are for the resistive strip and the wiper (the middle pin). Inside, the two outermost connection terminals are wired to the resistive element. This is usually wirewound and made of a material such as conductive plastic, carbon, or cermet. The wiper contacts the Ohmic component via the terminals. The wiper is a sliding contact and if it is moved along the track, the current flowing through the circuit changes. With mechanical trimmer potentiometers, this is achieved using a rotary switch, slide or screw. The divided Voltage is generated at the third connection terminal. For example, if 16V is applied and the potentiometer is fully adjusted to the positive contact, the third contact supplies the entire Voltage. However, if the potentiometer is set exactly between the positive and negative lines, the third connection terminal only has 8V - half of the Voltage potential. If the potentiometer is aligned with the negative connection terminal, the output potential is zero. It should be noted that these features only apply to potentiometers with a linear taper so do not apply to all variations. Digital Potentiometers Digital potentiometers use Field Effect Transistors (FETs) to control the flow of current. The resistor consists of several individual steps, which are determined by the number of position of the transistors. This contrasts with analogue or mechanical potentiometers, which use a mechanical resistor. Digital potentiometers typically offer more advantages than their analogue counterparts. For instance, they can be controlled with a digital input rather than manually needing to adjust a slide. Some digital potentiometers are volatile, meaning that they revert to a certain position as soon as they are switched off or disconnected from the mains. Digital versions are also resistant to shock and vibration unlike mechanical potentiometers, where movement could cause the wiper position to change. Lastly, digital models are advantageous as they can only be set by users able to access both the equipment and the programming interface.   Potentiometer Symbol The diagram to the left shows the standard symbol for a potentiometer as it would appear in a schematic. The design is straightforward - a simple augmentation of the standard resistor symbol. As potentiometers have three terminals, the arrow represents the third terminal (the wiper). Potentiometer Diagram The diagram to the right shows the role of a potentiometer in a circuit. The potmeter acts as an adjustable voltage divider, varying the wiper's position across the resistive material. The full input Voltage is applied across the resistor's length. As shown by the circuit diagram, the output Voltage is the Voltage drop - if any - between the fixed and sliding contact. Potentiometer Types Different types of potentiometers are intended for specific applications and environments. For instance, some industrial, heavy-duty models must be able to withstand extreme temperatures up to 150°C. Some of the most common potentiometer types are outlined below: Linear Potentiometer With linear potentiometers, the Voltage always changes linearly in constant steps depending on the rotation of the control unit and the location of the wiper on the resistive component. This type is commonly used in application like light dimmer switches.   Rotary Potentiometer Rotary potentiometers are designed for simple control via turning a knob or spindle. They can be either single turn or multi-turn, depending on the specific variety. Straightforward volume controls may only need a model with a single turn, whereas those that can be precisely adjusted might require multiturn models with up to fifteen turns.   String Potentiometer These components transform movement into an electrical signal. They may also be known as stringpots.   Logarithmic Potentiometer Logarithmic potentiometers are designed to change the potential in logarithmic increments. This type is often used with audio equipment to change the attenuation because the human perception of volume is non-linear.   Rheostat Potentiometer Potentiometers and rheostats are both variable resistors and the two components share several key similarities. However, the primary difference is the number of terminals. Rheostats have two terminals, whereas pots have three.   Slide Potentiometer Slide potentiometers change the resistance by sliding a wiper along a straight track. These components are also known as fader and slider potentiometers.   Trimmer Potentiometer These are principally used for calibrating and fine-tuning circuits. They are designed to allow for easy adjustment using a screwdriver, and it is also possible to mount them onto a printed circuit board (PCB) if required. Panel mount versions are common. This variation may also be known as trimpots.     Potentiometer Values Paying attention to the maximum resistance of a potmeter is an essential part of selecting the most suitable device. Potentiometer values can vary greatly between different models, so it is important to match this to the requirements of your intended application. For instance, if you will need the device to operate up to a maximum resistance of 1,000 Ohms, you should not choose a device that only covers up to 100 Ohms. Similarly, if you will be making very small, precise adjustments up to 10 Ohms, the chances are that you will not need a pot with a range up to 1,000 Ohms. You should also be aware that most standard potentiometers start at zero Ohms.   Potentiometer Characteristics Choosing the right potentiometer for your application and install environment is important. Factors that should be considered include the installation location, the required size, and the connection type needed. Although not all these properties will influence the device's electrical parameters, they must still be carefully considered to ensure that the pot can easily be accessed and adjusted where necessary. Another factor to bear in mind is the type of adjustment mechanism. With mechanical models, this could simply be choosing between a slide or rotary knob. However, in some applications, using a certain type or design will improve usability. Taper There are two taper types - logarithmic and linear. Your specific application will determine the taper type that you need. With a linear taper, the resistance between the wiper and the track will vary at a constant rate. If the wiper slides halfway along the track, the resistance will then be half of the total resistance. Conversely, the resistance doesn't vary at a consistent rate in devices with a logarithmic taper. Instead, the resistance moves down or up exponentially. This means that if the wiper slides halfway along the track, it will not produce resistance that is half of the total.

Potentiometers are a type of resistor that is used to manage the output signal of an electronic device such as a guitar, amplifier, or speaker. They have a small shaft on top that acts like a knob; when the user turns the shaft, the resistance to the signal increases or decreases. This change in resistance will alter the volume, gain, or power of the electrical signal.If you intend to install and wire a pot, it is very essential to ground the first terminal, feed the input signal into the third terminal, and then run an output signal through the terminal in the middle. To accomplish this, solder each wire to the corresponding terminal. Fortunately, if you've worked with soldering tools before, learning how to wire a potentiometer is a fairly simple process. Let us have a look at how to wire a Potentiometer? Part1：Selecting and Preparing a Pot   Place your pot on a flat surface step1: Determine the three main terminals that protrude from the center of the pot. Place your pot on a flat surface with the three prongs facing you. These are your access points. Your ground is located at the first terminal, or terminal 1. The middle terminal, or terminal 2, is the pot's input signal. The output signal is connected to the third terminal, or terminal 3. The top shaft is in charge of a small ring connected to the second terminal. By turning it, you can adjust how low or high the input is.   Look at the resistance numbers step2: Look at the resistance numbers on your pot to see what range you can achieve. Pots are rarely used to control signals higher than a few volts, but the amount of resistance they provide is significant. The greater the range, the greater your control over your device. The number on the front of the pot indicates the pot's maximum level of resistance. As a result, a 200K pot can provide a maximum resistance of 200,000 ohms. Tip: It is important to be aware of how much resistance a pot provides in order to determine whether or not it is appropriate for the task at hand. A 2,000-ohm pot won't provide enough range for a stereo system, but it should suffice for a dimmer switch.   three terminals step3: Place your pot on a flat surface so that the three terminals face you. Set your pot next to your electronic device on a flat surface. If you know you're going to install the pot in a specific location, begin there. Rotate the three terminals so that they face you. Remove any panels on your electronic device to expose any input or output ports on the backside. If you're using a breadboard, place the pot on the uppermost set of rows, terminals facing you. Before you open any panels or solder any connections, unplug your electronic device. You do not want to be electrocuted or permanently harm your device. cut 0.5–1 in (1.3–2.5 cm) step4: Any wires you intend to use should be measured and stripped. As long as the soldering wire is not acid-core, you can connect the terminals to the device with any genre of soldering wire. Measure each length of wire from the terminal to the device if you have an installation location set up. Strip any wires to expose the copper with a cutter. Cut and remove 0.5–1 in (1.3–2.5 cm) of plastic from the tip of each wire using the notches on the cutter's blades Set your wire stripper to match the gauge of the wire to ensure a clean strip. Get your soldering iron and flux ready on your work surfaceas you'll need to solder your wires. Plumbing makes use of acid-core soldering wire. It is incompatible with your electronics. If the soldering wires don't work, those insteadcan be used to wire a specific type of electronic device that requires specialized wires. Part2: Soldering Your Terminals step5: Connect a ground wire from terminal 1 on the left to the chassis. Tin a small length of wire by tapping it with your soldering iron and flux on the exposed part. After the wire has absorbed some flux, lower it and connect it to the exposed metal part on terminal 1. To connect the wire to the terminal, press your soldering tip against the connection. Solder the other end of the cable to any exposed, unpainted metal surface on your electronic device. If you want, you can use terminal 3 on the right, but you'll have to turn the knob clockwise to reduce the signal. Connect your device's output circuit to the middle terminal step6: Connect your device's output circuit to the middle terminal. Tin another length of wire in the same manner and connect it to the pot's middle terminal. Because this is where the signal enters the pot, it must be connected to the device's output. Solder the wire to the metal connection on the back of the output connection of your electronic device. The potentiometer's input is connected to the middle terminal. This means that the signal exits the electronic, enters terminal 2, and then exits terminal 3. As a result, terminal 2 must be connected to the port that sends the device's original signal out. This would imply connecting terminal 2 to the output jack on a guitar. This would imply connecting terminal 2 to the speaker output terminal of an integrated audio amplifier.   terminal 3 step7: Connect terminal 3 to the device's input. Terminal 3 is the output of the potentiometer. It is the location where the pot sends data back to the device. Tin a length of exposed soldering wire and place it directly on the terminal. Connect the wire to the input port of your electronic device after heating it with your soldering pen. Look for the exposed metal opening on the back of the knob or cable connection at the back of the port. To connect the pot, solder the wire directly to it. Terminal 3 is where the signal from your pot exits, so it must be wired to the location where you want to send the signal. This would imply connecting terminal 3 to the input jack on a guitar. Terminal 3 on an audio amplifier would be connected to the input channels.  Part3: Using Your Potentiometer Measure Potentiometer step8:Using a voltmeter, check that your pot is operational. Connect the voltmeter's terminals to the pot's input and output terminals. To feed a signal, turn on the voltmeter and turn the dial. To adjust the signal, turn the knob on top of your pot. Your potentiometer is operational if the signal reading on the voltmeter goes up and down as you turn the knob. If the voltmeter registers a signal from your pot but the device does not work when you turn your electronics on, there is a problem with the soldered connections.   signal from your pot step9: Turn the shaft to adjust the signal on your device. Turn on your electronic device and send a signal to the pot by playing music, striking a guitar note, or switching on a light. To reduce the volume or brightness, twist the shaft to the left. To increase the volume or level of light, twist the shaft to the right. To turn off the output, turn the shaft to the left. You can now adjust the amount of resistance that your signal receives by using your pot. adjust the amount of resistance       If you want, you can add a knob by sliding it over the potentiometer. If you prefer, you can install a potentiometer with the shaft bare and exposed. However, if you want to improve the aesthetics of your potentiometer, you can always purchase a knob. There are numerous knobs on the market that are designed to slide over the shaft of a pot and improve its appearance. That is all steps about how to wire a potentiometer. You can find what options are available for your specific make and model form online electronic stores.   If you want, you can add a knob by sliding it over the potentiometer.

As far as we know, resistors should always have two terminals; however, why does a potentiometer have three terminals and how do we use them? By looking at the diagram below, it is very simple to understand the purpose of these terminals.   Potentiometer pins   The diagram depicts the components found inside a potentiometer. We have a resistive track with a total resistance equal to the POT's rated resistance value. A potentiometer is nothing more than a resistor with one variable end, as the symbol implies. Assume we have a 10k potentiometer, and we measure the resistance between terminals 1 and 3 and get a value of 10k because both terminals are fixed ends of the potentiometer. Now, as shown above, we can place the wiper exactly at 25% from terminal 1, and if we measure the resistance between 1 and 2, we will get 25% of 10k, which is 2.5K, and measuring across terminals 2 and 3 will give us 7.5K. We can obtain variable resistance from terminals 1 and 2 or 2 and 3 and the knob can be used to vary the resistance and set the required value.
