    In a step-up transformer the turn ratio is 1:8. A lead accumulator \[(emf=6V)\] is connected across the primary coil of the .transformer. The voltage across the secondary coil is:

    A)  48 V           

    B)  0.75 V

    C)  14 V           

    D)  zero

    Correct Answer: D

    Solution :

     Key Idea: Lead accumulator battery is a DC power supply source. Transformer is based on the principle of mutual induction and works on AC power supply since lead accumulator is a DC source of supply, hence voltage across secondary is zero.
