Options

• watt

• ohm

• volt

• kWh

Answer 1

The unit for measuring potential difference is volt.

Explanation:

Potential difference is defined as the amount of work done to move a unit charge from one point to another in an electric circuit. It is measured using an instrument called a voltmeter, and its SI unit is the volt (V), named after the physicist Alessandro Volta. For context, the other options represent different electrical units: watt measures power, ohm measures resistance, and kWh measures commercial electrical energy.
