Q. In $NPN$ transistor, if doping in base region is increased then collector current
A) Increases
B) Decreases
C) Remains same
D) None of these
Explanation
(b) Number of holes in base region increases hence recombination of electron and hole are also increases in this region. As result base current increases which in turn decreases the collector current
