Transistor

Question

Statement I: When PN-junction is forward biased, then motion of charge carriers at junction is due to diffusion. In reverse biasing, the cause of motion of charge is drifting.
Statement II: In the following circuit, emitter is reverse biased and collector is forward biased

Moderate

A

Both statements I and II are correct.
B

Statement I is correct but statement II is incorrect
C

Statement I is incorrect but statement II is correct
D

Both statements I and II are incorrect.

Solution

In forward biasing of PN junction current flows due to diffusion of majority charge carriers. While in reverse biasing current flows due to drifting of minority charge carriers. The circuit given in the reason is a PNP transistor having emitter more negative w.r.t. base so it is reverse biased and collector is more positive w.r.t. base so it is forward biased.
