Q. The number of turns in the primary coil of a transformer is 200 and the number of turns in secondary coil is 10. If 240 V AC is applied to the primary, the output from secondary will be
A) 48 V
B) 24 V
C) 12 V
D) 6 V
Explanation
(c) $E_{S} = \frac{n_{s}}{n_{P}}E_{P} = \frac{1}{200} \times 240 = 12\ $V
