How is Electricity Made? | How Does Electricity Work?

How does electricity work? Electricity travels in closed circuits. It has to have a complete path before electrons can move through it. When you turn on a light by flipping a switch, you close a circuit. Of course, this means that by flipping a switch off, you open a circuit. Electricity flows from the electric wire, through the light, and back into the wire.
