The ratio of the number of turns of the primary to the secondary coils in an ideal transformer is 20: 1. If 240 V ac is applied from a source to the primary coil of transformer and a 6.0 Q resistor is connected across the output terminals, then current drawn by the transformer from the source will be-
(A) 4.0 A
(C) 0.97 A
(B) 3.8 A
(D) 0.10 A

Correct Answer : Option (D) 0.10 A
