5.22 Potentiometer
Potentiometer is also a resistance component with 3 terminals and its resistance value can be adjusted according to
some regular variation.
Potentiometers come in various shapes, sizes, and values, but they all have the following things in common:
• They have three terminals (or connection points).
• They have a knob, screw, or slider that can be moved to vary the resistance between the middle terminal and
either one of the outer terminals.
• The resistance between the middle terminal and either one of the outer terminals varies from 0 to the maximum
resistance of the pot as the knob, screw, or slider is moved.
Here is the circuit symbol of potentiometer.
The functions of the potentiometer in the circuit are as follows:
1. Serving as a voltage divider
