Q. In the case of forward biasing of a p-n junction diode, which one of the following figures correctly depicts the direction of conventional current (indicated by an arrow mark)?
A) [image:14_image81.emf]
B) [image:14_image82.emf]
C) [image:14_image83.emf]
D) [image:14_image84.emf]
Explanation
(a) In $p$-region direction of conventional current is same as flow of holes. In $n$-regoin direction of conventional current is opposite to direction of flow electrons.
