## Homework Statement

A typical power station produces 1000MW of electrical energy. Seven percent of the power is lost in a 500kV transmission line. Whats the lines resistance?

## Homework Equations

P=I

^{2}R

## The Attempt at a Solution

Thought this problem was simple but I keep getting it wrong.

P=I

^{2}R so P=V

^{2}/R

7 percent is lost @ 500Kv

so 0.97*1000*10

^{6}= (500*10^3)^2/R

R=268ohms but the actual answer is 17.5 ohms?

Thanks
