What happens in a closed circuit?

Back

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

Front

What happens in an open circuit?

Back

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

Front

What is the purpose of a switch in a circuit?

Back

The purpose of a switch is to open and close the circuit, controlling the flow of electricity.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves, which can be heard when they reach our ears.

Front

How does a battery work?

Back

A battery stores chemical energy and converts it into electric energy to power devices.

Front

What is a light bulb?

Back

A light bulb is a device that converts electric energy into light energy when electricity flows through it.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow from a power source to a device and back.
