How Much Power Is Lost Due to Resistive Heating in a High-Voltage Line?

[plexxity]

Homework Statement

A 750-MW power plant sends its power out on a 475,000 V high-voltage line. If the total resistance of the line is 0.65 Ω, what percentage of the power is lost due to resistive heating?

Homework Equations

i have NO idea but maybe...

P(loss)=I²R

P(loss)=^v²/R

P=V(V/R)

P=VI

V=IR

P=E/t

The Attempt at a Solution

Guess i don't know where to start

 

[Donaldos]

Use $$P=VI$$ to find $$I$$.

thanks i found I then i was able to get the Ploss=I^2(R)

got the answer Thanks!
