In the following figure, the diodes, which are forward biased, are

A

(c) only

B

(c) and (a)

C

(b) and (d)

D

(a), (b) and (d)

Text Solution

Verified by Experts

The correct Answer is:
B
Only in (a) and (C) diodes are forward biased as p-type should be higher potential & n-type at lower potential.
