Electricity

By Achsah Martin:)

Conductor

Conductors are materials that freely allow flow of electrons with very little resistance.

In the picture below, the conductor is flowing freely through the insulator.

Semiconductor

Semiconductors are materials that do not allow flow of electrons to flow freely but don't directly stop them either.

The picture below is a computer chip, which is made out of silicon(a semiconductor).

Insulator

Insulators are materials that greatly impede or stop the flow of electrons with very high resistance.

In the picture below, the insulator is stopping the conductor from shocking anything.

Compare and Contrast

They are alike because they all move or affect electrons.

They are different because a Conductor moves the most freely, a Semiconductor doesn't flow as freely but it doesn't completely stop, and an Insulator stops the flow of electrons with high resistance.

Real World Situations

-We use conductors to cook food on the stove, such as a metal pan.

-We use semiconductors to go on any computer or laptop.

-We use Insulators to keep anyone from getting electrocuted, such as the protecting around the wire on headphones.
