Insulators vs Conductors

An insulator is a material that does not allow electricity or heat to pass through it easily.

A conductor is a material that allows electricity or heat to pass through it easily.

Styrofoam is an example of an insulator.

Silver is an example of a conductor.

The circuit allows electricity to flow, which can power devices like light bulbs.

The circuit does not allow electricity to flow, so devices will not work.

Copper is NOT an insulator; it is a conductor.

Electrons in conductors are able to move easily, allowing electricity to flow.

Electrons in insulators are not able to move easily, preventing electricity from flowing.

Rubber is a common insulator used in electrical wires.
