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.

If unusually high currents exceed the capability of protective devices in the power system, a short-circuit can cause the devices to explode like a bomb.
