A high-voltage transmission line with a resistance of 0.30ohm/km carries a current of 1050 A. The line is at a potential of 670 kV at the power station and carries the current to a city located 164 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? %
W = AdeltaV
The Attempt at a Solution
first i did 1050A/1000 to convert that into 1.05 kA (not sure if this is correct)
then i did 1.05 x 670 = 703.5 kW or 703500 W (still not sure if I am doing this correctly)
that is when i get lost on how to do the next step, but from what i been doing i think i am doing it wrong and it will only lead me to confuse myself even more.
thanks for any help.
