For the given circuit of p-n junction diode which is correct :-
Updated On: Jul 9, 2024
- in forward bias the voltage across R is V
- in reverse bias the voltage across R is V
- in forward bias the voltage across R is 2V
- in reverse bias the voltage across R is 2V.
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
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 p, 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
So practically all the voltage will be dropped across the resistance p, 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
