Simple Definitions

The most important electronics terms, demystified in one place.


Our Take

A material that resists the flow of electricity. This is because the electrons in the materials are tightly bound to the nucleus, meaning it will take a lot of energy to pull that electron away. This gives insulators an extremely large band gap between the valence band and the conduction band.

Book Definition

A material that does not allow current to flow when voltage is applied, because of its high resistance.
