What you say makes sense. I had 45 years of AC system employment, wherein P
does not = EI. Wattless Power is measured and defined as reactive.
I hope the onlookers have had fun! Thank goodness that homopolar generator
discussion ended, remember the motor that gave useful work while generating
more than enough self- drive energy!   Cheers...ALEC
