    In a primary coil 5A current is flowing on 220 volts. In the secondary coil 2200V voltage produces. Then ratio of number of turns in secondary coil and primary coil will be [RPET 2003]

    A)            1 : 10                                        

    B)            10 : 1

    D)            11 : 1

    Correct Answer: B

    Solution :

               \[\frac{{{N}_{s}}}{{{N}_{p}}}=\frac{{{V}_{s}}}{{{V}_{p}}}=\frac{2200}{220}=\frac{10}{1}\]
