Q. Pick out the statement which is not correct
A) At a low temperature, the resistance of a semiconductor is very high
B) Movement of holes is restricted to the valence band only
C) Width of the depletion region increases as the forward bias voltage increases in case of a $N$-$P$ junction diode
D) In a forward bias condition, the diode heavily conducts
Explanation
(c) In case of a $N$-$P$ junction diode, width of the depletion region decreases as the forward bias voltage decreases
