  1. Question 1

    Q1. A full-wave rectifier is used to rectify an AC voltage of rms value 12 V. What is the average DC output voltage?

    • A) 10.8 V
    • B) 12 V
    • C) 15.3 V
    • D) 8.5 V

    Answer: 10.8 V

    Explanation: Vrms = 12 V, Vpeak = 12 * sqrt(2) = 16.97 V. Vdc = 0.637 * Vpeak = 10.8 V.
