I see the boys fom Ireland are to rake in over 2 million Euros this year selling development licences. I hope everyone here is n their Xmas lis for you effos promoting them.
It is al ur hope something usefull will come of this.
i think hey owe ou all a big thank you for yu efforts and many others like you. It certainly will make for a great Xmas for them
Kind Regards
Mark

I also think that the power source being used is constant current type or something non-ordinary, because I'm not getting a constant V/I ratio is excel sheet.
The R is also varying sinusoidally. Thats strange.

Like I said, impedance is irrelevant when Ohmic heating is calculated. For a given current it's only the Ohmic resistance that matters and that's frequency independent.
...

Any usefull work done by an electric generator to power a device, appears as a fictive resistance R// viewed from the generator, i.e here in parallel with the coil. R//*i² represents the energy that is consumed elsewhere in the circuit (in the core losses, or for doing work onto any external element coupled to the coil). "R primary is not a known value at every frequency", said Lumen, it is right but not enough. R// is missing in the circuittest.jpg scheme which is thus simply wrong.
Your mistake is to deal only with the coil ohmic resistance. It is irrelevant: you presume OU by ignoring the key element R// of the equivalent schematic and therefore you measure... OU!  Pure tautology, not real world.

This has already been clarified. Read for instance what @Omega_0 posted on the subject and try to understand it. This discussion is not in need of input by confused individuals.

@Omega_0,

All of this will become clear by using the current probe I got yesterday. I'm especially interested in the negative slope of the input energy in the case of the transformer which I'm not observing with the simple resistor. Will it be confirmed with the current probe?  Simple resistor shows OU at low as well as at high frequencies but the slope of the input current is never negative. Also, to mention it as a detail, with the transformer, the form of the current signal gets distorted at frequencies around 50Hz, apparently due to the core. Not in the case of the simple resistor. Also, simple resistor exhibits no I-V phase shift up to kHz frequencies after which inductance kicks in--you see I lagging behind V. I'll keep looking for the current probe supply today and hope I can find it sooner than the end of the month, as the company it was purchased from is expecting it. It's really aggravating to be held back by a simple power supply, having everything else needed to answer these important questions at once.
