Question

Device used to measure potential difference is _______.

Answer 1

1. The terminals of measuring instruments should be linked across the component where we expect a voltage drop to detect the potential difference.
2. We all know that a voltmeter is always linked across an electric component to detect the voltage drop.
3. Potential difference is the drop or rise in voltage.
4. As a result, we can say that a voltmeter measures the difference in electric potential.

Hence device used to measure potential difference is voltmeter.
