In an unbiased p-n junction

A)  Potential at p is more than that at n

B)  Potential at p is less than that at n

C)  Potential at p is equal to that at n

D)  Potential at p is +ve and that at n is -ve

Correct Answer: B

Solution :

Graph between potential and distance in a p n junction diode is given by Potential \[\therefore\] potential at p is less than that at n.
