What is a conductor?

Back

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

Front

What is an insulator?

Back

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

Front

What is a circuit?

Back

A circuit is a closed conducting circle or loop through which electric current can flow.

Front

Why is copper used in electrical wires?

Back

Copper is used in electrical wires because it is a good conductor, allowing electricity to flow easily.

Front

What happens when a circuit is open?

Back

When a circuit is open, the flow of electricity is interrupted, and devices connected to the circuit will not work.

Front

What is the role of a switch in a circuit?

Back

A switch is used to open or close a circuit, controlling the flow of electricity.

Front

Why does plastic feel warm when sliding down a slide?

Back

Plastic feels warm because it is a good insulator, which means it does not conduct heat away from the body quickly.

Front

Can you name a common insulator found in homes?

Back

Common insulators found in homes include rubber (used in electrical cords) and glass (used in windows).

Front

What is the difference between conductors and insulators?

Back

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

Front

Give an example of a good conductor and a good insulator.

Back

A good conductor is copper, and a good insulator is rubber.
