[QUOTE="helotaxi, post: 3625473, member: 550915"] But in typical Fryman fashion he only knew enough to not know exactly what he was talking about. HS physics FTL. Just enough knowledge to be dangerous. He assumed that since there is a phase difference between voltage and current with a reactive load, that you needed to account for that difference when figuring power applied. The problem with that logic is that if it were true, it would break Ohm's law because V would not equal I*R at any point in time. Actual power applied at any instant is not important because as I sad before, it's the current that does the work. The voltage induces the current IAW Ohm's law. That peak voltage and peak current don't occur at the same time is irrelevant. Welcome to reactive loads. Welcome to driver phase response. [/QUOTE]
