What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.

Front

Which material is a good conductor?

Back

Copper is a good conductor of electricity.

Front

Which material is a good insulator?

Back

Rubber is a good insulator and is often used to cover electrical wires.

Front

What happens when a conductor is connected to a battery?

Back

When a conductor is connected to a battery, electricity flows through the conductor, allowing devices to work.

Front

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

Is water a conductor or an insulator?

Back

Water can conduct electricity, especially if it contains impurities, making it a conductor.

Front

What is the difference between a conductor and an insulator?

Back

Conductors allow electricity to flow easily, while insulators resist the flow of electricity.
