Insulators vs Conductors

Front

What is the definition of an insulator?

Back

An insulator is a material that does not allow the flow of electric current or heat due to tightly bound electrons.

Why do conductors allow electricity to flow?

Back

Conductors allow electricity to flow because they have loose electrons that can move freely.

Front

Why do insulators not allow electricity to flow?

Back

Insulators do not allow electricity to flow because they have tightly bound electrons that do not move freely.

What is the role of an oven mitt in cooking?

Back

An oven mitt acts as an insulator to protect hands from heat when handling hot objects.

Front

Is iron a conductor or an insulator?

Back

Iron is a conductor.

Front

What happens to electrons in a conductor when voltage is applied?

Back

Electrons in a conductor move freely, allowing electric current to flow.

Front

What happens to electrons in an insulator when voltage is applied?

Back

Electrons in an insulator remain tightly bound and do not move, preventing electric current from flowing.
