Potentiometer
A potentiometer is a variable resistor with three terminals whose voltage is adjustable manually with the help of a movable contact in order to control the flow of electric current through it.
- Symbol
- The input voltage is applied across the two end terminals and the output is taken between the first end terminal and the sliding contact.
- The output voltage will be taken across any one of the two input terminals and the sliding contact.
