What is an insulator?

Back

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

Front

What is a conductor?

Back

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

Front

Why is plastic used to cover electrical wires?

Back

Plastic is used to cover electrical wires because it is a good insulator, preventing electricity from escaping and reducing the risk of fire.

What is the best example of a conductor?

Back

A metal bowl is the best example of a conductor.

Front

What property makes metals useful for electrical wiring?

Back

Metals are useful for electrical wiring because they are good conductors of electricity.

Front

What happens to plastic when it is heated?

Back

Plastic can melt when heated, which is why it is important to use it as insulation in electrical applications.

Name a common insulator used in electrical applications.

Back

Plastic is a common insulator used in electrical applications.

Front

What is the role of insulation in electrical wiring?

Back

The role of insulation in electrical wiring is to prevent the flow of electricity outside the wire, protecting against short circuits and fires.

Front

Why are metals not considered insulators?

Back

Metals are not considered insulators because they allow electricity to flow through them easily.
