    Question

    In half-wave rectifier, what is the output frequency if

    the input frequency is 40 Hz. What is the output frequency of a full-wave rectifier for the same input frequency?
    A 80 Hz Correct Answer Incorrect Answer
    B 82 Hz Correct Answer Incorrect Answer
    C 85 Hz Correct Answer Incorrect Answer
    D 90 Hz Correct Answer Incorrect Answer

    Solution

    Input frequency = 50Hz For a half-wave rectifier, input frequency is equal to the input frequency. Output frequency = 40Hz For a full-wave rectifier, the output frequency is twice the input frequency. Therefore, Output frequency = 2 × 40 = 80 Hz
