Physics · Class 12 · CBSE — Alternating Current
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 \(6.0 \Omega\) resistor is connected across the output terminals, then current drawn by the transformer from the source will be-
- 4.0 A
- 3.8 A
- \(0.97 {~A}\)
- 0.10 A
Answer
(D) 0.10 A
