(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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? %

2. Relevant equations

W = AdeltaV

3. 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 im 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.
