Which device provides electrical energy to run an electric circuit
Asked by maham237 @ in Physics viewed by 420 People
A. The wire
B. The switch
C. The battery
D. The light bulb
Answered by maham237 @
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.
