provide a conductor for energy to flow from one place to another.
provide an insulator to slow the flow of energy.
what is the difference between a conductor and an insulator?
a conductor allows electricity to flow through it easily and an insulator does not.
an insulator allows electricity to flow through it easily and a conductor does not.
a conductor is magnetic and an insulator is not.
an insulator is magnetic and a conductor is not.
