Conductors and Insulators

Front

What is a conductor?

Back

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

What is an insulator?

Back

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

Which material is a good conductor of electricity?

Back

Metal is a good conductor of electricity.

Front

Which material is a good insulator of electricity?

Back

Plastic is a good insulator of electricity.

Front

Why are wires often covered in plastic?

Back

Wires are covered in plastic because plastic is an insulator, which helps prevent electric shocks.

Front

What happens when electricity passes through a conductor?

Back

When electricity passes through a conductor, it can power devices like lights and motors.

Front

What happens when electricity tries to pass through an insulator?

Back

When electricity tries to pass through an insulator, it cannot pass through, which helps protect us from electric shocks.
