Q. In the following circuit of $PN$ junction diodes $D_{1},\ D_{2}$ and $D_{3}$ are ideal then $i$ is

A) $E/R$
B) $E/2R$
C) $2E/3R$
D) Zero
Explanation

(a) Diodes $D_{1}$ and $D_{3}$ are forward biased and $D_{2}$ is reverse biased so the circuit can be redrawn as follows
$\Rightarrow i = \frac{E}{R}$
