Let's say you got this circuit given which works as a Wien oscillator. To my understanding here Ri is the negative feedback loop and the total impedance of R3 & R4 & L2 & R1 are the feedback loop.
To get the total complex power consumed by the positive feedback loop, I assumed to use the formula: S = [(Vo - Vi)(Vo - Vi)°] / Z°(positive feedback loop)
( with ° meaning the complex conjugate )
However I keep getting the wrong answers, so is there another way to calculate the complex power in the positive feedback loop?
