One way in which the operation of a n-p-n transistor differs from that of a p-n-p (a) The emitter junction injects minority carriers into the base region of the p-n-p (b) The emitter injects holes into the base of the p-n-p and electrons into the base region of n-p-n (c) The emitter injects holes into the base of n-p-n (d) The emitter junction is reverse biased in n-p-n

Answer: (b). In both types the emitter junction is forward biased and injects carriers that are minority carriers in the base. The difference is the type of carrier: holes in p-n-p, electrons in n-p-n. So the answer is (b).

Junction Transistor

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

Show answer and solution

Answer: (b)

In both types the emitter junction is forward biased and injects carriers that are minority carriers in the base.
The difference is the type of carrier: holes in p-n-p, electrons in n-p-n.
So the answer is (b).
