Insulators vs Conductors

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, typically because it has loose electrons.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, usually because it has tight electrons.

Front

Why do insulators not allow the flow of electricity?

Back

Insulators do not allow the flow of electricity because they have tight electrons.

Front

Is glass an example of an insulator?

Back

True, glass is an example of an insulator.

Front

Which of the following is NOT an insulator: Wool, Plastic, Copper, Glass?

Back

Copper is NOT an insulator.

Front

Why do electrons move so easily in conductors?

Back

Electrons move easily in conductors because they have loose electrons.

Front

What is an example of a good conductor?

Back

Aluminum foil is a good conductor.

Front

What happens to the flow of electricity in an insulator?

Back

The flow of electricity is blocked or restricted in an insulator.

Front

Can rubber be considered an insulator?

Back

Yes, rubber is considered an insulator.

Front

What is the role of electrons in conductors?

Back

In conductors, electrons are free to move, allowing electricity to flow.
