Experiment 6 meter checking of transistor.

When testing B.J.T (bipolar junction transistor) you switch the multi meter to diode test mode, you would perform this test to find out which is the BASE COLLECTOR and EMITTER.

There are 2 types... the PNP and the NPN type

To check BJT you would first measure using multi meter on the diode setting to find out which is PNP and NPN once you distinguish which is which you would then easily find the base...collector and emitter...the emitter base juntion usually has a higher forward VD. This is due to the difference in the doping concentration between the emitter and collector of the BJT.
