Question

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

1:10
10:1
1:1
11:1

The correct answer is: 10:1

$fraction numerator N subscript s end subscript over denominator N subscript p end subscript end fraction equals fraction numerator V subscript s end subscript over denominator V subscript p end subscript end fraction equals fraction numerator 2200 over denominator 220 end fraction equals fraction numerator 10 over denominator 1 end fraction$
