Transistors - NPN & PNP - Basic Introduction

This electronics video tutorial provides a basic introduction into NPN and PNP transistors which are known as BJTs or Bipolar Junction Transistors.  This video discusses the 3 operating regions of a transistor - the cutoff, active, and saturation region.  It also explains how the transistors act as switches and how to determine the current and voltages in a transistor base bias circuit.
