A potentiometer is an adjustable electronic component. It consists of a resistive body and a rotating or sliding system. By manually adjusting the shaft or the sliding handle and changing the position of the movable contact on the resistor body, the resistance value between the movable contact and any fixed end is changed, thereby changing the magnitude of the voltage and current. 

Double potentiometer is a kind of synchronous adjustment potentiometer with two sets of resistance substrates, such as two-channel audio. If you use two ordinary potentiometers to adjust the volume, it is a very troublesome thing. Usher is very convenient. The multi-connected potentiometer is also a synchronous adjustment potentiometer, which can be made into a human factor potentiometer, and has many applications in audio and electronic equipment to achieve synchronous adjustment.
