The instrument used to measure potential difference is Voltmeter.
Voltmeter
A voltmeter is a tool that measures the voltage or potential difference between two points in an electrical circuit. The voltmeter is always connected parallel. There are two types of voltmeters
- Digital voltmeter
- Analogue voltmeters
Some voltmeters are built for use in DC circuits, while others are built for use in AC circuits. Ohm’s law regulates the activity of a voltmeter.
