1. The problem statement, all variables and given/known data Consider, in the circuit from the image, i1(t) = 5 cos(2t + 10º) v1(t) = 10 cos(2t - 60º). Find the value of the current ix(t). Options given: A: ix(t) = 9.9 cos(2t - 129.2º) B: ix(t) = 9 cos(2t - 29.2º) C: ix(t) = 99 cos(2t + 129.2º) D: ix(t) = 0.99 cos(2t + 130º) 2. Relevant equations Ohm's law. V=IR 3. The attempt at a solution My aproach was, first calculate the amount of current produced by the voltage source, combining the R + C + L in series and ignoring the current source, the result was 2<-59º(or 1.03 -1.7j) After I calculated the amount of current from the current source. I ignored the voltage source (short circuiting the circuit) and calculated L || (C + R) and the amount of current going to (C + R) is 11.86<-25.3º (or 10.7 -5.06j). Finally i summed the currents: 1.03-1.7j + -(10.7-5.06j) ====> negative because it goes in the opposite direction from the one in the image. The result was -9.67+3.36j or 99.7<-19.16º [+180º]; That is 99.7 < 160.84º or 99.7 cos(2t + 160.84º) That is near option C but not exactly! What am I doing wrong? Thanks for any help.
