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.

How does a transistor work? Asked by: Tony Whelan Answer The design of a transistor allows it to function as an amplifier or a switch. This is accomplished by using a small amount of electricity to control a gate on a much larger supply of electricity, much like turning a valve to control a supply of water.
