Q. If $n_{e}$ and $v_{d}$ be the number of electrons and drift velocity in a semiconductor. When the temperature is increased
A) $n_{e}$ increases and $v_{d}$ decreases
B) $n_{e}$ decreases and $v_{d}$ increases
C) Both $n_{e}$ and $v_{d}$ increases
D) Both $n_{e}$ and $v_{d}$ decreases
Explanation
(a) Because $v_{d} = \frac{i}{(n_{e})eA}$
