Print. An electric circuit is like a pathway made of wires that electrons can flow through. A battery or other power source gives the force (voltage) that makes the electrons move. When the electrons get to a device like a light bulb, your computer, or a refrigerator, they give it the power to make it work.The word âcircuitâ sounds like âcircle,â and a circuit needs to be circular to work. battery or other power source gives the force (voltage) that makes the electrons move.

Switches are used to switch the loads on and off whenever necessary. Hence, the source, the load, and the switch are connected together to form electrical circuits. The circuit is called 'closed' when the current flows in the circuit, and when the current does not flow, it is called an 'open circuit'. The switch or key helps to make or break the circuit, i.e. switches on or switches off the current. Sub Topics. Components of An Electric Circuit.
