Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow, connecting a power source to electrical devices like light bulbs.

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily. Examples include rubber, plastic, and wood.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily. Examples include metals like copper and aluminum.

Front

What is a battery?

Back

A battery is a device that stores chemical energy and converts it into electrical energy to power circuits.

Front

What happens when a circuit is incomplete?

Back

When a circuit is incomplete, electricity cannot flow, and devices like light bulbs will not work.

Front

What is a light bulb?

Back

A light bulb is a device that produces light when electricity passes through it.

Front

What is the role of wires in a circuit?

Back

Wires connect different components in a circuit and allow electricity to flow between them.

Front

What is a complete circuit?

Back

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

Front

What is a switch?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.
