Conductors and Insulators

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

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

Plastic is an insulator.

Rubber is a good insulator.

Copper is a conductor.

An insulator slows down energy transfer.

A lunchbox can be an example of an insulator used to regulate temperature.

No, an insulator cannot be a good conductor.

Insulators are used in electrical wiring to prevent electricity from escaping and to protect people from electric shocks.

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