Question

Interpret the significance of the battery in the following simple circuit

Answer 1

Answer:

The role of a battery (or cell) in an electric circuit is to supply energy to the circuit by doing work upon the charge to move it from the low energy terminal to the high energy terminal.

A battery is a source of energy which provides a push - a voltage - of energy to get the current flowing in a circuit. A bulb uses the electrical energy provided by the battery, but does not use current. When the energy in the battery is used up there is no current and the bulb does not light up.
