Front

What is a power source in a circuit?

Back

A power source provides the energy needed to move electric charges through the circuit, such as a battery.

Front

What is the function of a switch in a circuit?

Back

A switch controls the flow of electricity by opening (off) or closing (on) the circuit.

Front

What happens when a switch is closed?

Back

When a switch is closed, it completes the circuit, allowing electric current to flow and power devices like bulbs.

What does it mean for a light to be 'on' in a circuit?

Back

A light is 'on' when electric current is flowing through it, allowing it to emit light.

Front

What is the role of wires in a circuit?

Back

Wires connect different components of a circuit, allowing electric current to flow between them.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow.

Front

What is an open circuit?

Back

An open circuit is a broken loop where current cannot flow, often due to a switch being open.

Front

What is the purpose of connecting wires to a battery?

Back

Connecting wires to a battery allows the battery to provide power to the circuit.
