A transistor works by using a small amount of electricity to control a much larger supply of electricity, much like turning a valve to control a supply of water.

Transistors consist of three main parts - a base, a collector, and an emitter.

The base is the part for the larger electrical supply. The collector is the larger electrical supply, and the emitter emits that supply. By sending different levels of currents from the base, the size of the current can be regulated to the collector In this way, a very small amount of current may be used to control a large amount of current, like an amplifier.

ANSWER: A VOM can identify the transistor as NPN PNP just by checking the diodes inside the transistor. Example NPN positive lead to base should show low resistance to the other terminals
