For the given circuit of `PN`-junction diode, which of the following statements is correct? A. In reverse biasing the voltage across R is 2 VB. In forward biasing the voltage across R is 2 VC. In forward biasing the voltage across R is VD. In reverse biasing the voltage across R is V |

Answer» Correct Answer - C 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. |
