Question

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

Answer 1

Answer: (A)

In forward biasing the voltage across R is V

Answer 2

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