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
For forward bias, p-type should be at higher potential and n-type at lower potential. Hence (a) and © are in forward bias.
