1. The problem statement, all variables and given/known data Calculate the power (Pso) absorbed from the supply by the transmission line on open circuit. Given parameters are: A1= 0.8698 A2= 0.03542 B1= 47.94Ω B2= 180.8Ω C1= 0S C2= 0.001349S D1= 0.8698 D2= 0.03542 I have calculated Vs and Is earlier in the question Vs= 77325 + j3149V Is= j119.93A 2. Relevant equations 3. The attempt at a solution I don't know where to start with this one to be honest and haven't got any real direction from my course notes. Can i use equation P=I^2*R? I suspect it's more complicated than that!
