  1. Question 1

    Q1. The current gain of a transistor in CB configuration is 0.98. The change in collector current for a change in emitter current of 5 mA is

    • A) 4.9 mA
    • B) 3.9 mA
    • C) 2.9 mA
    • D) 1.9 mA

    Answer: 4.9 mA

    Explanation: α = ΔIc / ΔIe, so ΔIc = α * ΔIe = 0.98 * 5 mA = 4.9 mA.
