The potentiometer is a resistance element with three terminals and the resistance
value can be adjusted according to a certain change law, which is equivalent to a
variable resistor. Because its role in the circuit is to obtain a certain relationship with
the input voltage (external voltage) to output Voltage, so called potentiometer.
Potentiometers can be divided into rotary potentiometers, push-pull potentiometers,
straight slide potentiometers, etc. according to the adjustment method. Our course
experiment uses a rotary potentiometer.Its three pins are showed as below:
The rotary potentiometer is an adjustable resistance element. It is composed of a
resistor and a rotating system. When a voltage is applied between the two fixed
contacts of the resistive body, the position of the contact on the resistive body is
changed by the rotating system, and a voltage that has a certain relationship with the
position of the moving contact can be achieved between the moving contact and the
