Ok, then what your saying is that E rms squared/R=Average Power.
If that is so, and as one post said Average Power = appx .9 X RMS Power then
Average power/.9 should = RMS Power.
Also then, what does E average squared/R=?
It seems to me that Schrader taught RMS power was E rms Squared/R
Maybe I am getting to old to remember--Hi!
