Is copper a conductor or an insulator?

Back

Copper is a conductor.

Front

What happens in a closed circuit?

Back

In a closed circuit, electricity can flow freely, allowing devices like lights to turn on.

Front

What happens in an open circuit?

Back

In an open circuit, electricity cannot flow, which means devices like lights will not turn on.

What is the role of conductors in electrical circuits?

Back

Conductors allow electricity to flow through the circuit, powering devices.

Front

What is the role of insulators in electrical circuits?

Back

Insulators prevent the flow of electricity, protecting us from electric shocks.
