    The turn ratio in a step up transformer is 1: 2. If a cell of 1.5 V is connected across the input, then the voltage across the output will be

    A) 0.1 V   

    B)        1.5 V

    C) 0.75 V  

    D)         zero

    Correct Answer: D

    Solution :

    [d] A transformer cannot step up a d.c. input so output potential here will be zero. No potential will be induced in the secondary coil.
