Question

A transistor is operated in common emitter configuration at constant collector voltage V $_{c}$ = 1.5 V such that a change in the base current from 100 $μ$ A to 150 $μ$ A produces achange in the collector current from 5 mA to 10 mA. The current gain ( $β$ ) is:-

Solution

The correct option is D 100
$β$ = $\frac{Δ I_{C}}{Δ I_{B}}$ = $\frac{(10 - 5) \times 10^{- 3}}{(150 - 100) \times 10^{- 6}}$ = 100
