Question

Which of the following devices can be udlsed to maintain potential difference between two of conductor​

Answer 1

Answer:

Potential difference can be defined as the difference in the amount of energy that charge carriers have between two points in a circuit.

Explanation:

An ammeter. source of electricity such as cell, battery, power supply, etc. helps to maintain a potential difference across a conductor. A voltmeter is an instrument used for measuring the electrical potential difference between two points in an electric circuit.
