MCQ (Single Correct Answer)
In figure given below, 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
