  1. Question 1

    Q1. A transistor amplifier has a collector current of 5 mA and a base current of 50 μA. What is the current gain (β) of the transistor?

    • A) 99
    • B) 100
    • C) 101
    • D) 102

    Answer: 100

    Explanation: β = Ic / Ib = 5 mA / 50 μA = 100. Option A is incorrect due to not using exact values.
