A) In forward biasing the voltage across R is V
B) In reverse biasing the voltage across R Is 2V
C) In forward biasing the voltage across R is 2V
D) In reverse biasing the voltage across R is 2V
Correct Answer: A
Solution :
Key Idea: In forward biasing, ideal junction diode has zero resistance and infinite resistance in reverse biasing. In forward biasing, the diode conducts. For ideal junction diode, the forward resistance is zero. Therefore, entire applied voltage occurs across resistance R i.e., there occurs no voltage drop. While in reverse biasing, the diode does not conduct, so it has infinite resistance. Thus voltage across R is zero in reverse biasing.
