Materials that don't allow electrons to flow freely but doesn't directly stop them either.

Examples : silicon, computer chips

Materials that greatly impede or stop the flow of electrons with very high resistance.

Examples : glass, dry air, and rubber

Compare and Contrast

Amount of Resistance:

- Conductors < Semiconductors < Insulators

- They are all the same because they all are materials that affect electrons.

How you find them in your daily life :

- Conductors are found in ovens, to cook our food.

- Semiconductors are found in computers, cell phones, etc. that we use every day.

- Insulators like the rubber around your charger, the insulator prevents you from shocking yourself.
