A power transmission line feeds input power at 2400 V to a step-down transformer with its primary windings having 5000 turns. The output power is delivered at 240 V by the transformer. If the current in the primary coil of the transformer is 5 A and its efficiency is 95% then the current in the secondary will be |
50 A 47.5 A 45 A 4.75 A |
47.5 A |
The correct answer is Option (2) → 47.5 A |
