    Question

    The Maximum Power transfer theorem states that maximum

    power is delivered when_______
    A Load resistance is half of source resistance. Correct Answer Incorrect Answer
    B Load resistance is thrice of source resistance. Correct Answer Incorrect Answer
    C Load resistance is twice of source resistance. Correct Answer Incorrect Answer
    D Load resistance is equal of source resistance. Correct Answer Incorrect Answer

    Solution

    The Maximum Power Transfer Theorem states that for a linear network with a source of internal resistance, the power delivered to the load is maximum when the load resistance exactly matches the source (Thevenin) resistance. At this point, the load receives the highest possible power, although efficiency is only 50% because half of the power is lost in the source resistance.
