Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.

Which materials let electricity flow through them?
Materials that allow electricity to pass through them are called conductors. Copper wire is a good conductor. Materials that do not allow electricity to pass through them are called insulators. Plastic is a good insulator.
Do insulators allow electricity to flow freely?
In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.
What allows charges to flow freely?
Conductors are materials that permit electrons to flow freely from particle to particle. An object made of a conducting material will permit charge to be transferred across the entire surface of the object.
