    A transformer has 1500 turns in the primary coil and 1125 turns in the secondary coil. If the voltage in the primary coil is 200 V, then the voltage in the secondary coil is

    A)  100 V                                   

    B)  150 V

    C)  200 V                                   

    D)  250 V

    Correct Answer: B

    Solution :

                     From the relation \[\frac{{{N}_{1}}}{{{N}_{2}}}=\frac{{{V}_{1}}}{{{V}_{2}}}\] Given,                 \[{{N}_{1}}=1500,\,{{N}_{2}}=1125,\,{{V}_{1}}=200\,volt\]                                 \[{{V}_{2}}=?\]                 \[\therefore \]  \[\frac{1500}{1125}=\frac{200}{{{V}_{2}}}\]                 \[\Rightarrow \]               \[{{V}_{2}}=\frac{200\times 1125}{1500}\] \[=150\,\,\text{volt}\]
