You can watch MHB Channel01 on youtube. In this 5:14 Minutes video, we have shown you how to test transistors (NPN and PNP) with an analog multimeter. Under the test, the NPN Transistor has a number C945 and PNP A1015. • The pin connections of both transistors are as below: If you hold anyone transistor in your hand as its terminals are placed towards the ground. The terminal at your right hand is the base and on the left hand is the emitter. And the base is placed in the middle. Attach black probes on the base terminals and red probes connected with the collector and the emitter one by one. The meter will show low resistance by the movement of the needle on a scale provided in the meter. which is an indication of both junctions are forward biased. Changes to the probes and meter will show NO deflection. Which is an indication of reverse bias. • Now opening the base terminal and connecting both probes across the emitters and the collector terminals. The meter will show No deflection, which is an indication of NO leakage current. It shows that the transistor is in good condition and able to use it. • The whole procedure and indications will be changed in the case of a PNP transistor. Keep in mind that in the case of an analog multimeter Red probe contain a negative battery and a Black probe having a positive battery. • Please subscribe to my channel for more videos • #mhbchannel01 • • Video • Please watch: Remember ALLAH almighty on time every time • • Remember ALLAH almighty on time every... • ~-~~-~~~-~~-~ • Please watch: Transformerless LED Tube Light • • Transformerless LED Tube Light • https://channel for technical and career-building videos • • Working of Transistor part-2 • • DC Analysis and Current Model of Tran... • ~-~~-~~~-~~-~
