How does an insulator work?
An insulator does not work like a normal material. It does not allow electricity to flow freely through it. This is because an insulator does not have a atom in it that is capable of holding an electric charge.
instead, it has a hole in it. The hole is big enough for electricity to flow through, but small enough that it does not touch the inside of the insulator.

Why is electrical conductivity important?
Electricity is important because it is the flow of electricity through wires that make things like machines work. Electricity flows in one direction and it is easy to see why this is so – when you have a wire that is long and thin, the electric current that flows through it is in the same direction as the wire itself! This is why you see wires running in all directions around a room – the current is in the same direction as the wire itself!
