Circuits, Conductors, and Insulators

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily. Examples include metals like copper and iron.

Front

What is an insulator?

Back

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

Front

What is a circuit?

Back

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

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow.

Front

What is an open circuit?

Back

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

Front

What is the role of a battery in a circuit?

Back

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

Front

What materials are good conductors?

Back

Good conductors include metals like copper, aluminum, and iron.

Front

What materials are good insulators?

Back

Good insulators include rubber, glass, wood, and plastic.

Front

What happens when a circuit is broken?

Back

When a circuit is broken, the flow of electricity stops, and devices connected to the circuit will not 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.
