engineering physics MCQ #1832

  1. Question 1

    Q1. In a common emitter amplifier, the input resistance is 1 kΩ and load resistance is 3 kΩ. If β = 100, voltage gain is

    • A) 100
    • B) 200
    • C) 300
    • D) 400

    Answer: 300

    Explanation: Voltage gain = β * (R_load / R_input) = 100 * (3 / 1) = 300, using the formula for voltage gain in a common emitter amplifier.
