obviously is zero. And still there are other phases to deal with. This I don't understand. Let me elaborate.

For example when calculating the amount of stored energy at resonance, then you can visualize that the energy goes back and forth between capacitor and inductor. So they are not in phase, but are in fact out of phase by ##\pi /2##, or rather the current is.

Now my question is: In what equation (or diagram) is this clearly marked?
