For a common emitter circuit if Ic/Ie = 0.98 then current gain for common emitter circuit will be

1. 49
2. 98
3. 25.5
4. 6

Correct answer: 98

Solution

The current gain (β) for a common emitter circuit is given by β = Ic/Ib, where Ib = Ie - Ic. Given Ic/Ie = 0.98, we can calculate β as β = 0.98 / (1 - 0.98) = 98.
