    Question

    What is used as a conventional regulator for controlling

    fan speed?┬а┬а
    A Capacitor Correct Answer Incorrect Answer
    B Resistor Correct Answer Incorrect Answer
    C Transformer Correct Answer Incorrect Answer
    D None of the above Correct Answer Incorrect Answer

    Solution

    Conventional fan regulators use resistors to control fan speed. By varying the resistance, the voltage across the fan changes, which adjusts its speed. Higher resistance results in lower fan speed due to reduced voltage.
