Q. In an unbiased $p-n$ junction
KCET
KCET 2008
Semiconductor Electronics: Materials Devices and Simple Circuits
A
Potential at $p$ is more than that at $n$
24%
B
Potential at $p$ is less than that at $n$
33%
C
Potential at $p$ is equal to that at $n$
22%
D
Potential at $p$ is $+ve$ and that at $n$ is $-ve$
21%
Solution:
Graph between potential and distance in a $p-n$ junction diode is given by
$\therefore $ potential at $p$ is less than that at $n$
