We really like this model because it goes a long way to shed light on some of the more subtle features of BJT transistors for beginners. For example, the simplest “electronic switch” model ...

Using a transistor ... control circuits. We’ve embedded his twenty-minute video after the break. In it he talks about the use of transistors, the difference between NPN and PNP transistors ...

Also called a "bipolar junction transistor" (BJT), it is one of two major transistor categories; the other is "field-effect transistor" (FET). Although the first transistor was bipolar and the ...
