Explanation:

Potentiometer and Voltmeter

A potentiometer is a device that is used to measure the potential difference in a circuit. We know that potential difference is the amount of work done in bringing a charge from one point to other. When there is a potential difference in a circuit, the current flows through the circuit. The unit of potential difference is measured in volts. The potential difference of a circuit can be measured by a voltmeter.
