The light-bulb theory

What do you need to light a bulb??? The answer, electricity provided via two wires, the live wire (also referred to as phase) and the neutral wire. The live wire is the one with a switch and the neutral is usually connected to the bulb at all times, to help it glow when ever the live wire is connected to it.

A pretty bright idea ain't it???
