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

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...

i have Power=k(19.4C-(-6.1C)) k isn't given in the problem?

so what would the value of k be then? that's what i can't figure out.

Thanks you guys are awesome

Homework Statement If only conductive heat loss was significant for a house, then by what percentage would you lower the heat loss if the temperature was reduced inside from 73°F to 67°F, when the outside temperature is 21°F? (Hint: Try using a ratio.) Homework Equations Unknown The...
