What is the purpose of a switch in a circuit?

Back

A switch is used to open or close a circuit, controlling the flow of electricity.

Front

What happens when a circuit is closed?

Back

When a circuit is closed, electricity flows through the circuit, powering devices like light bulbs.

Front

What happens when a circuit is open?

Back

When a circuit is open, electricity cannot flow, and devices will not work.
