Q. 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
A) 1 : 10
B) 10 : 1
C) 1 : 1
D) 11 : 1
Explanation
(b) $\frac{N_{s}}{N_{p}} = \frac{V_{s}}{V_{p}} = \frac{2200}{220} = \frac{10}{1}$
