Front

What is a circuit?

Back

A circuit is a closed path through which electric current flows.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it, such as wood or rubber.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as copper or aluminum.

Front

What happens when a switch is closed?

Back

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

Front

What happens when a switch is open?

Back

When a switch is open, it breaks the circuit, stopping the flow of electricity.

Front

What is a battery?

Back

A battery is a device that stores electrical energy and provides power to a circuit.

Front

What is a light bulb?

Back

A light bulb is a device that converts electrical energy into light energy.

Front

What materials are needed to create a complete circuit?

Back

You need a power source (like a battery), conductors (like wires), and a load (like a light bulb).

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening or closing the circuit.
