Front

What does a battery do in a circuit?

Back

A battery provides the energy needed for the circuit to work.

Front

What is an open circuit?

Back

An open circuit is a broken path where electricity cannot flow, so devices like light bulbs do not light up.

Front

What is a closed circuit?

Back

A closed circuit is a complete path that allows electricity to flow, enabling devices like light bulbs to light up.

Front

What is an insulator?

Back

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

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 if you cut a wire in a circuit?

Back

Cutting a wire creates an open circuit, stopping the flow of electricity and causing devices to turn off.

Front

What is the role of a light bulb in a circuit?

Back

A light bulb converts electrical energy into light energy when electricity flows through it.
