1. The problem statement, all variables and given/known data A1 = 5A, A2 = 4A, A3 = 3A. V = 120V a) Given the circuit above, find A4 b) Find the angle between E and IT. Draw a diagrammatic (?) and find the power in the circuit. c) Find the values of R, L and C. 2. Relevant equations 3. The attempt at a solution a) IT is 5A. R has 120V across it, and 4A through it. Therefore ZR = 30Ω∠0° L has 120V across it, and 3A through it. Therefore ZL = 40Ω∠90° C has 120V across it, and xA through it. I'm not sure how to proceed here. Can I use admittance, somehow? I'm thinking I should be able to find the angle of the current through the R and L components (the current should be 0° and 90°?) Whatever's left goes through the capacitor (at -90°?). How can I figure out how to compute this?
