MCQ
In $NPN$ transistor, if doping in base region is increased then collector current
- AIncreases
- ✓Decreases
- CRemain same
- DNone of these
✓
Answer
Correct option: B.
Decreases
b
(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.
