NEETPhysicsSemiconductor ElectronicsMCQ+4 / −1
For the given circuit of p-n junction diode which is correct

AIPMT 2002 Physics - Semiconductor Electronics Question 40 English
  1. A
    in forward bias the voltage across R is V
  2. B
    in reverse bias the voltage across R is V
  3. C
    in forward bias the voltage across R is 2V
  4. D
    in reverse bias the voltage across R is 2V.
View written solutionFree

Correct answer: A

In forward biasing, the resistance of p-n junction diode is very low to the flow of current. So practically all the voltage will be dropped across the resistance R, i.e. voltage across R will be V.

In reverse biasing, the resistance of p-n junction diode is very high. So the voltage drop across R is zero.
