What is an electrical conductor?

Back

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

Front

What is an example of a common electrical conductor?

Back

Copper is a common electrical conductor, often used in wiring.

Front

Why is copper commonly used in electrical wiring?

Back

Copper is used in electrical wiring because it has high electrical conductivity, meaning it can efficiently carry electric current.

Front

What happens when a switch in a circuit is closed?

Back

When a switch is closed, it completes the circuit, allowing electricity to flow and power devices like buzzers or lights.

Front

What is a complete circuit?

Back

A complete circuit is a closed loop that allows electricity to flow from a power source, through a load, and back to the power source.

Front

What is an incomplete circuit?

Back

An incomplete circuit is an open loop where electricity cannot flow due to a break or gap in the circuit.

Front

How can you complete an incomplete circuit?

Back

You can complete an incomplete circuit by connecting the two open ends with a conductor, such as a wire.

Front

What is an electrical insulator?

Back

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

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to drive the current through the circuit.

Front

What is the function of a switch in an electrical circuit?

Back

A switch controls the flow of electricity in a circuit by opening (breaking the circuit) or closing (completing the circuit) it.
