NOTE: The horizontal axis of the characteristic curve plot were mislabeled as Vbe instead of Vce in one or two spots. The downloadable video notes have been corrected. This is a back-to-basics tutorial video on the bipolar junction transistor, or BJT. While there are just two basic types (NPN and PNP), the video mainly discusses NPN types. It reviews the schematic symbol, typical pinouts, & basic operating principles of linear and switch operation. We dip our toe into the physics a little bit, and then do some experiments on the bench to demonstrate the linear and switch / saturation mode of operation. Links to the notes and other videos appear below the chapter listing:
