1. The problem statement, all variables and given/known data A 400kV line is carrying 1GW of power and experiences a line resistance of 5 ohms. What is the power loss in the cable due to resistive losses? 2. Relevant equations 3. The attempt at a solution You are given 4 potential answers to this question a) 3.2x10^7 W b) 78 W c) 5000 W d) 2x10^8 W I have tried using I=P/V and then substituting this value into P=I^2/R but this doesn't seem to give any of the answers. Can anyone help me out?
