Question

Which device provides electrical energy to run an electric circuit

Answer 1

The correct answer is

C. The battery

The battery is a device that provides a potential difference in the circuit, and so an electromotive force (e.m.f.) which pushes the electrons in the circuit from the negative pole towards the positive pole of the battery, so they move through the circuit. Therefore, it provides electrical energy.

Answer 2

The energy comes from the battery, power supply, generator, wall outlet, solar panel, or windmill.
