Question

define : potential difference and electric cell​

Answer 1

Answer:

In a conductor, electrons flow only when there is a difference in electric pressure at its ends. This is also called potential difference. In a circuit, this potential difference is created by a battery. A battery or a cell has a potential difference due to reaction of chemicals inside it even when it is not connected to any circuit.
