1. The problem statement, all variables and given/known data
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?

2. Relevant 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

3. The attempt at a solution

Guess i dont know where to start

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

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