RLC circuit inductor/capacitor combined voltage?? I have an RLC circuit. I understand that the combined sum of the voltage magnitudes across the three components will be greater than the signal generator. I don't understand, however, why the combined voltage across the inductor and the capacitor will always be greater than zero? Isn't the voltage sign of these two components opposite? And if so, as one is increasing and the other is decreasing, wouldn't there be a moment when the sum equaled zero? Thanks for any input on this. It's driving me crazy. p.s. for clarity, i'm wondering why the sum of the voltage across the inductor and capacitor is always greater than zero?
