Question

A transistor is connected in common emitter (CE) configuration. The collector supply is 8 V and the voltage drop across a resistor of 800 Ω in the collector circuit is 0 . 8 V . If the current gain factor α is 0 . 96 , then the change in the base current is, 1 24 mA, 1 12 mA, 1 6 mA, 1 3 mA

According to the question : α = 0.96 β = α 1 - α = 0.96 1 - 0.96 = 24 Δ I C = 0.8 800 = 10 - 3 A Δ I B = Δ l C β = 10 3 24 A = 1 24 mA
