The current gain α of a transistor in common base mode is 0 . 995 . Its gain β in the common-emitter mode is
Options
- A200
- B99
- C199
- DNone of these
Correct answer
C. 199
Step-by-step solution
The current gain α of a transistor in common base mode is 0.995 β is current gain in the common emitter mode β = α 1 - α = 0.995 1 - 0.995 = 199
