If 30 MW of power at 45kV (rms) arrives at a town from a generator via 4-ohm transmission lines, calculate the fraction of power generated that is lost in the lines.(adsbygoogle = window.adsbygoogle || []).push({});

okay I think I'm not completely understanding what I'm supposed to do in this question, or I'm missing something as from my calculations there is more than 100% power loss

P/V = I

30,000,000W/45,000V = 666.7 A

Pl = I^2 x R

666.7^2 x 4 = 1777955.56V = 1778kV

probably something completely stupid that I'm doing here so would appreciate it if someone can set me straight, thnx

----edit-----

sorry stupidity strikes again... forgot that the power lost comes out in W not V

:yuck: duh! sorry again, it's fine now
