    Question

    A load resistance R_L is supplied from a dc voltage source of resistance R. Maximum power transfer to the load occurs when which of the following condition is satisfied?

    A.

    RL<RR_L < R​​

    B.

    RL=R/2R_L = R/2​​

    C.

    RL>RR_L > R​​

    D.

    RL=RR_L= R​​

    Correct option is D

    For a DC circuit, the Maximum Power Transfer Theorem states that:Maximum power is transferred from the source to the load when the load resistance is equal to the internal resistance of the source.Thus,RL=R\text{For a DC circuit, the Maximum Power Transfer Theorem states that:} \\[8pt]\text{Maximum power is transferred from the source to the load when the load resistance is equal to the internal resistance of the source.} \\[12pt]\text{Thus,} \\[8pt]R_L = R​​
