What is a conductor?

Back

A conductor is a material that allows the flow of electric current or sound easily. Examples include metals like copper and aluminum.

What is an insulator?

Back

An insulator is a material that does not allow the flow of electric current or heat easily. Examples include rubber, plastic, and glass.
