1. The problem statement, all variables and given/known data I need help with determining the current through the 1Ω resistor. http://img403.imageshack.us/img403/5422/acex22.jpg [Broken] The trouble I have is that the voltage sources are phased as given in picture, and I got stuck on how to deal with these phases when calculating the current with impendance. I know I need to count the impendance, but I get the wrong answer when I count the current from every source (superposition theorem). 2. Relevant equations If I look at it through the superposition theorem and current divider rule, I should get the correct answer with regards to current through the 1 Ω resistor. I am absolutely certain that I don't do the voltage right, i.e. 5 Δ 30 and 5 Δ -30 . Is this correct thinking? 3. The attempt at a solution Back to superposition theorem, I can count the total impendance for every voltage source. Then I divide the voltage, example (5 Δ 30) / Z Δ ω = I From there I go to the current divider rule and count the current through the resistor per source. This is repeated with the upper source as: (5 Δ -30) / Z Δ ω = I ------------------ I've handled these problems well without the voltage phases, but I don't think I handle the voltage phases rather well here. I would really appreciate any pointers on how to proceed!
