What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, such as rubber or glass.

What happens when a circuit is incomplete?

Back

When a circuit is incomplete, electricity cannot flow, and the devices in the circuit will not work.

Front

What is resistance in an electrical circuit?

Back

Resistance is a measure of how much a material opposes the flow of electricity, affecting how much current can flow.
