• Potentiometers are three terminal resistors with one contact, known as the wiper, which slides across the device in order to create a variable voltage divider. They can also be used with just 2 terminals connected in which case they behave like a variable resistor or rheostat. Potentiometers are a common choice for human interface devices since they can easily be made to resemble a dial or track slider.

  
  

  How Potentiometers Work

  What Is A Voltage Divider?

  A voltage divider is a network of resistors that is used to reduce the voltage by some factor. The simplest form of voltage divider is a pair of resistors in series. For example, say you have two 10k resistors in series and nothing else connected to a 12V power supply. The following diagrams shows the voltages at various points in the divider:

• 

• The voltage at the point between the 2 resistors is proportional to Vcc, and the ratio of the resistors. For example if the resistors were 5k and 10k instead of 2 10k then the voltage would be 8V. If the resistors were 10k and 5k, the voltage would be 4V.

  
  

  There are 3 pieces to a potentiometer

  These are the reference terminals of the potentiometer. You connect Vcc and Gnd to A and B in order to power your voltage divider.

  This is a resistive material of some kind. It is often graphite though other common materials include resistance wire, carbon particles in plastic, and a ceramic/metal mixture called cermet. In a linear potentiometer, this would be a straight line as opposed to a circular track.

  The final piece is the wiper. The wiper acts as a third terminal which moves over the resistive section of the device thereby changing the resistance on either side of it. In the case of a rotational potentiometer like the one illustrated above, the wiper is mounted on a pivot point and it can then be adjusted with a knob or screwdriver etc... In a slider style potentiometer the wiper would sit in a track and behave like the sliders on an audio equalizer. As the wiper nears the Vcc terminal, the voltage on the wiper terminal increases. It decreases as the wiper nears the Gnd terminal.

• 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.

• Application scenarios of different types of potentiometers

• 

  Linear potentiometer

  Suitable for circuits that require continuous adjustment of voltage or current, such as volume control, brightness adjustment, etc.

  

  Switching potentiometer

  Suitable for circuits that require switching functions, such as relay control, signal switching, etc.

  

  Digital potentiometer

  Suitable for circuits that require digital signal adjustment, such as microcontroller interfaces, digital signal processing, etc.

• How to choose a potentiometer

  When choosing a potentiometer, the following key factors need to be considered

  Resistance range: The resistance range of the potentiometer should meet the requirements of the circuit. When choosing, pay attention to whether the maximum and minimum resistance values are within the allowable range of the circuit.

  Power: The power of the potentiometer should be sufficient to withstand the voltage and current in the circuit to avoid overheating or damage.

  Accuracy: Select a potentiometer with appropriate accuracy based on the circuit's requirements for resistance accuracy. High precision potentiometers are suitable for circuits that require strict resistance values.

  
  

• 

• Rotation angle or stroke: For rotary potentiometers, it is necessary to choose the appropriate rotation angle or stroke to ensure that it can provide the required range of resistance changes in the circuit.

  Material and Structure: The material and structure of a potentiometer can affect its durability and stability. Choosing appropriate materials and structures can improve the service life and performance of potentiometers.

  Price and brand: On the premise of meeting performance requirements, price and brand factors can be considered to choose potentiometers with high cost-effectiveness.
