Question

A step-up transformer works on 220V and gives
2 A to an external resistor. The turn ratio between
the primary and secondary coils is 2:25.
Assuming 100% efficiency, find the secondary
voltage, primary current and power delivered
respectively
1) 2750V, 25 A, 5500 W 2)2750 V, 20 A, 5000 W
3) 2570 V, 25 A, 550 W 4) 2750 V, 20 A, 55 W​
