Conductors and Insulators

Front

What is a conductor?

Back

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

Front

Which material is the best conductor of electricity?

Back

Copper is the best conductor of electricity among common materials.

Front

What happens to heat when it passes through a conductor?

Back

Heat moves quickly through a conductor, making it warm.

Front

What happens to heat when it passes through an insulator?

Back

Heat moves slowly through an insulator, keeping the material cool.

Front

Give an example of a good insulator.

Back

Wool is a good insulator that helps keep heat in.

Front

What is the role of insulators in electrical wiring?

Back

Insulators protect us from electric shocks by covering the conductive wires.

Front

How do conductors and insulators differ in terms of heat transfer?

Back

Conductors allow heat to transfer easily, while insulators slow down heat transfer.

Front

Why do we use rubber on electrical cords?

Back

Rubber is used on electrical cords because it is an insulator that prevents electric shock.

Front

What is one property of metals that makes them good conductors?

Back

Metals have free electrons that allow electricity to flow easily.
