A high-voltage transmission line with a resistance
of 0.29 Ω/km carries a current of 1045 A. The
line is at a potential of 660 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?
MW
(b) What fraction of the transmitted power does this loss
represent?
%
