    A battery of internal resistance 4Q-is connected to the network of resistances as shown. In order that the maximum power can be delivered to the network, the value of R in \[\Omega \] should be

    A) 4/9          

    B)                                    2

    C) 8/3         

    D)                                    18

    Correct Answer: B

    Solution :

    Power delivered by the battery will be maximum when effective resistance of external circuit is same as internal resistance of the battery. Effective resistance of external circuit = 2R (Due to balanced wheatstone bridge) Hence 2R = 4                 \[R=2\Omega \]
