Semiconductor Electronics Materials Devices And Simple Circuits Ques 74
74. One way in which the operation of a $n-p-n$ transistor differs from that of a p-n-p
[NEET Kar. 2013]
(a) the emitter junction is forward biased in $n-p-n$
(b) the emitter junction injects minority carriers into the base region of the n-p-n
(c) the emitter injects holes into the base of the p-n-p and electrons into the base region of $n-p-n$
(d) the emitter injects holes into the base of p-n-p
Show Answer
Answer:
Correct Answer: 74.(c)
Solution:
- (c) In p-n-p transistor holes are injected into the base while electrons are injected into the base of n-p-n transistor. Emitter-base junction is forward biased.
