Q. 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
Explanation
(b) Graph between potential and distance in a p-n junction diode is given by
[image:14_image204.emf]
$\therefore$ potential at $p$ is less than that at $n$.
