Explain the difference between a conductor of electricity and an insulator. Give an example of each.

• A conductor allows electricity to flow through it easily, like copper; an insulator does not, like rubber.

• A conductor does not allow electricity to flow through it, like rubber; an insulator allows it, like copper.

• A conductor and an insulator both allow electricity to flow through them easily.

• A conductor and an insulator both do not allow electricity to flow through them.
