The long and the short of it is that when AC encounters a reactive
load, it results in a current that is not in phase with the voltage.
Power is equal to volts x amps only when the current and voltage are
in phase.... which can only happen if the load is purely resistive.
If you hang a perfect capacitor across the power line, or a perfect
inductor, you will draw lots of current, but no power.
