A transistor is operated in common emitter configuration at VC=2V. Such that a change in the base current from 100 μA to 200 μproduces a change in the collector current from 5 mA to 10 mA. The current gain is
A
100
B
150
C
75
D
50
Answer
50
Explanation
Solution
: current gain,
β=ΔIBΔIC=(200−100)×10−6(10−5)×10−3=50
