In the following figure, the diodes which are forward biased, are A. In the following figure, the diodes which are forward biased, are A. B. C. D.
B.In the following figure, the diodes which are forward biased, are A. B. C. D.
C.In the following figure, the diodes which are forward biased, are A. B. C. D.
D.In the following figure, the diodes which are forward biased, are A. B. C. D.

Options

  1. AC only
  2. BC and A
  3. CB and D
  4. DA, B and D

Correct answer

B. C and A

Step-by-step solution

For forward bias p-type should be higher potential and nn-type at lower potential. Hence (A) and (C) are in forward bias.
