Question

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 verse
• 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.

Answer 1

Answer: (B)

$D_{2}$is forward biased and $D_{1}$ is reverse biased and hence no current flows from B to A and vice verse

Answer 2

: Diode$D_{1}$is reverse biased as p side is connected to negative potential and n side to ground.
