Conductor - materials that allow electrons to flow freely through them.

Semi-conductor - materials that allow electrons to flow but with some resistance.

Insulator - materials that have a high resistance and do not attract electricity.

Differences and Similarties

Conductors and Semi-conductors both can let electrons flow through them. Conductors allow electrons to flow freely along its material, and semi-conductors have a resistance against electrons flowing through its material and do not flow as freely as conductor materials. Insulators do not allow to flow of electricity through its material and does not attract electricity.


An example of a conductor would be: iron, copper, and water

An example of a semi-conductor would be: silicon, and carbon

An example of insulators would be: rubber, and glass
