Here is the question: A high Voltage line with a resistance of .18 ohms/km carries a curent of 1525A. The line is at a potential of 1500 kV at the powerstation and caries to current to a city located 192 km away. What is the power loss due to resistance in the line. Answer in units of MW. I throught P =IV was all i had to do. Now i'm thinking i need to calculate the total power. Then calculate the power with resistance in it and subtract the two. I'm not sure how to do the power with resisatance. I'm think i used use P=v^2/R but i think i need to conver the ohms out of ohm/km.
