Conductors and Insulators

Front

What is a conductor?

Back

A conductor is a material that allows electricity or heat 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 electricity or heat to flow through it easily. Examples include rubber, plastic, and wood.

Front

Which material is a good conductor of electricity?

Back

Copper is one of the best conductors of electricity.

Front

Which material is a good insulator?

Back

Rubber is a good insulator and is often used to cover electrical wires.

Front

What happens to heat when it passes through a conductor?

Back

Heat passes through a conductor easily, making it warm.

Front

What happens to heat when it passes through an insulator?

Back

Heat is slowed down or blocked by an insulator, keeping the material cool.

Front

Can insulators conduct electricity?

Back

No, insulators do not conduct electricity well.

Front

What is an example of a good conductor of heat?

Back

Metals like copper and aluminum are good conductors of heat.

Front

What is an example of an insulator used in homes?

Back

Materials like fiberglass and foam are used as insulators in homes to keep them warm.

Front

Why are conductors important in electrical circuits?

Back

Conductors are important because they allow electricity to flow, enabling devices to work.
