In figure , assuming the diodes to be ideal ,

A

`D_1` is forward biased and `D_2` is reverse biased and hence current flows from A to B.

B

`D_2` is forward biased and `D_1` is reverse biased and hence no current flows from B to A and vice versa.

C

`D_1 and D_2` are both forward biased and hence current flows from A to B.

D

`D_1 and D_2` are both reverse biased and hence no current flows from A to B and vice versa

Text Solution

Verified by Experts

The correct Answer is:
B
Diode `D_1` is reverse biased as p side is connected to negative potential and n side to ground.
Diode `D_2` is forward biased as p side is grounded and n side is at negative potential.
