The most important electronics terms, demystified in one place.


Our Take

A material that varies in its level of conductivity, not truly an insulator nor truly a conductor. This is done by using the correct material, adding impurities to it, and then using applied voltages. This means that, among several things, they can be used like switches, conducting or not conducting as needed.
