1. The problem statement, all variables and given/known data 2. Relevant equations P = 1/2 Vm*Im*cos(θv - θi) 3. The attempt at a solution First I added all the impedance values to find the total impedance seen by the source. Zt = j10 + (50 || 20 + j10) = 15 +j5 Ω Now since the circuit is not purely resistive, I can't just go Vrms^2 / R to find the average power. So I divided 240 by the total impedance to find I. I = 240 / (15 + j5) = 8 - j8 A (rms) The answer I get is as follows. P = 1/2 240*(8-j8)*cos(45°) = 678.8 - j678.8 W Am I correct in how i solved the problem? Thanks in advance.
