Question

write the steps to identify emitter, base and collector terminals of given transistor

Answer 1

If you have a NPN bipolar transistor, you will find a PN junction that is formed from the base to the collector and another will be from collector to emitter. So, you can easily identify the base of the transistor.

If your multimeter has a voltage drop option, you can check the one with the higher drop in voltage will be the emitter and the one with the lower voltage drop is the collector
