1. The problem statement, all variables and given/known data I have a coil that is connected to 60hz, 100V ac generator. At this frequency, the coil has an impedance of 11.1 ohms and a reactance of 8.8 ohms. I need to find what series capacitance is required so the the current and voltage are in phase. 2. Relevant equations X(L) = X(c) ; X(L) = 1 / (wc) 3. The attempt at a solution I have tried implemented the solution above, but I don't seem to be getting the correct answer. Any help would be greatly appreciated.
