For the given circuit of `PN`-junction diode, which of the following statements is correct?

Options

A. In reverse biasing the voltage across R is 2 V
B. In forward biasing the voltage across R is 2 V
C. In forward biasing the voltage across R is V
D. In reverse biasing the voltage across R is V

Answer

C

Explanation

For an ideal junction diode, the forward resistance is zero and hence there is no voltage drop across it, when it is forward biased. Hence voltage across R is V. Option (c). But in reverse biasing it does not conduct. It has infinite resistance.
`therefore` Voltage across the diode is V and voltage across R is zero.
