What is an electrical circuit?

Back

An electrical circuit is a closed loop that allows electricity to flow from a power source, through conductors, and back to the power source.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical circuit through which current can flow.

Front

What is an open circuit?

Back

An open circuit is a broken circuit where electricity cannot flow.

Front

What is an electrical conductor?

Back

An electrical conductor is a material that allows electricity to pass through it easily, such as copper or aluminum.

Front

What is an electrical insulator?

Back

An electrical insulator is a material that does NOT let electricity pass through it, such as rubber or glass.

Front

What role does a switch play in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening (turning off) or closing (turning on) the circuit.

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 lights.

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's function in a circuit?

Back

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

Front

What is a light bulb in a circuit?

Back

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