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 n -type at lower potential. Hence (A) and (C) are in forward bias.
