Front

Is aluminum foil a conductor or an insulator?

Back

Aluminum foil is a conductor.

Front

What is the primary characteristic that distinguishes conductors from insulators?

Back

Conductors have free electrons that allow electricity to flow, while insulators have tightly bound electrons.

Front

What happens to the flow of electricity in an insulator?
