MCQ (Single Correct Answer)
A transistor is operated in common emitter configuration at constant collector voltage VC = 1.5 V such that a change in the base current from 100 $$\mu $$A to 150 $$\mu $$A profuces a change in the collector current from 5 mA to 10 mA. The current gain $$\beta $$ is
A
50
B
67
C
75
D
100
Explanation
Current gain, $$\beta $$ = $${{\Delta {I_C}} \over {\Delta {I_B}}}$$
