Question

Question: An n-p-n transistor circuit is arranged as shown in the figure. It is aye common
(1.) Base amplifer circuit
(2) Emitter amplifer circuit
(3) Collector amplifer circuit
(4.) None of these
​

Answer 1

Answer:

Correct option is B)

An NPN transistor circuit is arranged as shown in figure. It is A common emitter amplifier circuit because emitter (N) is common to both, base (P) and collector (N).
