One Way In Which The Operation Of A Npn Transistor Physics Question

One way in which the operation of a n-p-n transistor differs from that of a p-n-p

Options

(a) the emitter junction is reserved biased in n-p-n
(b) the emitter junction injects minority carriers into the base region of the p-n-p
(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 n-p-n

Correct Answer:

the emitter injects holes into the base of the p-n-p and electrons into the base region of n-p-n

Explanation:

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.
