Answer 2

Answer:

Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit. **Measured in Volts: **Potential difference (p.d.) is measured in volts (V) and is also called voltage. ... We use a voltmeter to measure potential difference (orvoltage).
