Open in App

Solution

Voltmeter:
It is an instrument used to measure the potential difference across two terminals in a circuit.
It can measure the voltage of the order millivolts to the order of kilovolts.
It is connected in parallel to the source across which the voltage is to be measured.
So, the function of a voltmeter in an electric circuit is to measure the potential difference.
