Question

In a CE transistor, a change of 8.0 mA in the emitter current produces a change of 7.8 mA in the collector current. What change in the base current is necessary to produce the same change in the collector current?

​ Δ I E ​ = Δ I C ​ + Δ I B ​ Δ I E ​ = 8 mA , Δ I C ​ = 7.8 mA ∴ Δ I B ​ = Δ I E ​ − Δ I C ​ = 8 − 7.8 = 0.2 mA = 200 μ A ​
