A Potentiometer is a popularly used electronic component to vary or
control the amount of current flowing through an electronic circuit. The
instrument is a three-terminal resistor having a sliding contact. In
case all three terminals are used, the equipment can also act as a
variable voltage divider. It was earlier used to measure the voltage or
potential in an electric circuit.It is also considered to be a potential divider, where the sliding connection is made user friendly and adjustable with the help of a knob or slider.
