A battery is a device that helps to maintain a potential difference between across a conductor.

• It consists of one or more electric cells.

( Since a battery is a source of electricity.)

• Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit.

NOTE

• A voltmeter measures potential difference.

• A battery maintains the potential difference.
