00:00The question is, the part of a transistor which is heavily doped to produce a large number
00:11of majority carriers is A base, B emitter, C collector, D none of these.
00:21Like a suppose, this is a NPN transistor, so this is emitter and this is base and this
00:35is collector.
00:39Otherwise, the function of emitter is to provide large number of majority charge carriers,
01:08and base controls the flow of current between emitter and collector and base is lightly
01:34doped and collector collapse the charges and it is moderately doped.
01:41So, the correct option will be B emitter.
01:48So, the correct option will be B emitter.
01:55The correct option will be B emitter.
02:02B emitter.
02:09B emitter.
