    A battery of emf 10V and internal resistance 0.5 ohm is connected across a variable resistance R. The value of R for which the power delivered in it is maximum is given by :

    A)  0.5 ohm                              

    B)  1.0 ohm              

    C)         2.0 ohm              

    D)         0.25 ohm

    Correct Answer: A

    Solution :

    We know that for obtaining maximum power, the internal resistance must be equal to variable resistance so, the value of R will \[0.5\,\Omega \].
