Q. If $N_{P}$ and $N_{e}$ be the numbers of holes and conduction electrons in an extrinsic semiconductor, then
A) $N_{P} > N_{e}$
B) $N_{P} = N_{e}$
C) $N_{P} < N_{e}$
D) $N_{P} > N_{e}$ or $N_{P} < N_{e}$ depending on the nature of impurity
Explanation
The correct answer is Option D: $N_{P} > N_{e}$ or $N_{P} < N_{e}$ depending on the nature of impurity.
