Why are metals used for electrical wires?

Back

Metals are used for electrical wires because they allow electric current to flow freely.

Front

What happens if you use an insulator in a circuit?

Back

If you use an insulator in a circuit, the electric current will not flow, and devices like bulbs will not light up.
