The unit of measurement of electric current. It is proportional to the quantity of electrons flowing through a conductor past a given point in one second. It is analogous to cubic feet of water flowi [..]

The path that electricity follows.

 Material that allows electric current to pass through it.

 The rate of flow of electricity in a circuit, measured in amps.

 A machine that transforms mechanical energy into electricity. It consists of a magnet rotating in a coil wire, which frees electrons and pushes them along the wire.

 The earth or any object that makes an electrical connection with the earth, which has an arbitrary zero potential energy level.

 Anything touching an electrical current and ground at the same time is "grounded."

 Material that strongly resists the flow of electricity through it.

 A collection of equipment for the purpose of raising, lowering and regulating the voltage of electricity.

 An electrical device that either raises or lowers the voltage of electricity.
