Q58 / 120 · NEET 2011 (Mains) · Physics
In the following figure, the diodes which are forward biased, are
A. 
B.
C.
D.

B.

C.

D.

- AC only
- Correct answerBC and A
- CB and D
- DA, B and D
Solution
For forward bias p-type should be higher potential and $n$-type at lower potential. Hence (A) and (C) are in forward bias.
Hence, the correct answer is option: 'B'.
