Q. For the given circuit of $PN$-junction diode, which of the following statement is correct

A) In forward biasing the voltage across $R$ is $V$
B) In forward biasing the voltage across $R$ is $2V$
C) In reverse biasing the voltage across $R$ is $V$
D) In reverse biasing the voltage across $R$ is $2V$
Explanation

(a) In forward biasing, resistance of $PN$ junction diode is zero, so whole voltage appears across the resistance
