Question

What is the purpose of an electric cell in the circuit?

Answer 1

1. An electrical cell is a bank or reservoir for an “electrical power supply”.
2. In the cell internally it converts stored chemical energy into electrical potential energy allowing a current to flow from the positive terminal to the negative terminal via an external circuit.
3. Hence, it maintains the rate of flow of charge in the circuit, i.e., it maintains the flow of electric current in the circuit.
