    A cell of internal resistance \[1.5\,\Omega \] and of e.m.f. 1.5 volt balances 500 cm on a potentiometer wire. If a wire of \[15\,\Omega \] is connected between the balance point and the cell, then the balance point will shift                                                                           [MP PMT 1985]

    A)                    To zero                           

    B)            By 500 cm

    C)                    By 750 cm

    D)                    None of the above

    Correct Answer: D

    Solution :

                 Balance point has some fixed position on potentiometer wire. It is not affect by the addition of resistance between balance point and cell.
