4. 0.707 A

 A small town with a demand of 800 kW of electric power at 220 V is situated 15 km away from an electric plant generating power at 440 V. The resistance of the two wirelines carrying power is 0.5 $\Omega$ per km. The town gets power from the line through a 4000-220 V step-down transformer at a sub-station in the town. The line power loss in the form of heat is:

1. 100 kW
2. 500 kW
3. 400 kW
4. 600 kW
