A high-voltage transmission line with a resistance of 0.34 omegacap.gif/km carries a current of 960 A. The line is at a potential of 750 kV at the power station and carries the current to a city located 165 km from the station.
(a) What is the power loss due to resistance in the line?
W
(b) What fraction of the transmitted power does this loss represent?
%
