Transistor : How to Test - NPN or PNP and Emtter, Base, Collector | TECH GURUKUL HD

How to Test a Transistor : NPN or PNP and Terminals : Emtter, Base, Collector | TECH GURUKUL This video gives you an easy way to test a transistor using a digital Multimeter. In short, to determine what type of transistor - By swapping positive and negative probes until you get 2 forward bias voltage readings , for example 1 positive probe on one pin and another two pin is on negative probe then it is an NPN transistor and vice - versa for PNP transistor. To determine the which pin is emitter, base and collector. Emitter = forward bias voltage is higher than collector pin Collector = lower forward bias voltage compared to emitter pin Base = reference probe for both two junctions in forward bias
