    In a step-up transformer, the turn ratio is 1 2 . A Leclanche cell (emf = 1.5 V) is connected across the primary. The voltage developed in the secondary would be

    A)  3.0V                                     

    B)  0.75V

    C)  1.5V                                     

    D)  zero

    Correct Answer: D
