Q. In the following, which one of the diodes is reverse biased?
A) [image:14_image117.emf]
B) [image:14_image118.emf]
C) [image:14_image119.emf]
D) [image:14_image120.emf]
Explanation
(d) For reverse biasing of an ideal diode, the potential of $n$-side should be higher than potential of $p$-side. Only option (d) is satisfying the criterion for reverse biasing.
