A high-voltage transmission line with a resistance of 0.315 Ω/km carries a current of 1.45 kA. The line is at a potential of 750 kV at the power station and carries the current to a city located 161 km from the power station. What is the power loss due to resistance in the line? What fraction of the transmitted power does this loss represent?
