    In the circuit shown in figure, the current drawn from the battery is 4A.  If 10 W resistor is replaced by 20 W resistor, then current drawn from the circuit will be [KCET 2000; CBSE PMT 2001]

    A)         1 A

    B)         2 A

    C)         3 A

    D)         0 A

    Correct Answer: D

    Solution :

                                             Given circuit is a balanced Wheatstone bridge circuit. So there will be no change in equivalent resistance. Hence no further current will be drawn.
