BJT Transistors – Electronics Switches and Inverters

This video tutorial explains how Bipolar Junction Transistors can be used as electronic switches and as inverters. As a switch, a small current flowing into the base can be used to activate a larger current flowing in another circuit. As an inverter, it flips the output state. If the input is low, the output will be high. This video also explains how to use ohm’s law and kirchoff’s law to solve a simple NPN transistor circuit.
