STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

[Omnibus]

Omnibus has at least presented some better results at lower Hz, which totally contradict his early claims, but the higher frequency results are questionable and may only be artifacts. The majority of his statements are still only true in Omni world but not in the real world. Only a couple rebuttals follows:
Not true, that is why the formula for inductance reactance (XL) was developed, which changes with frequency.

Not true, the formula for impedance is Z = square root of R^2 + XL^2. XL has a frequency factor in its formula.

I'm done with Omni world for a while, got other important things to do, does anybody else want to bang their head against the Omni truth barrier for a while?

On the contrary, dissipative (Ohmic) resistance is not known to be a function of frequency neither does R in Z = square root of R^2 + XL^2. XL. R is not frequency dependent. That's elementary.

Try silver wire. But I am not sure it will help what you are trying.

Unfortunately, silver isn't much better than copper: http://www.tpub.com/content/neets/14176/css/14176_17.htm

In discussing the results I'm presenting there is a very limited choice of parameters one can juggle with. Only three, in fact--dissipative resistance (active resistance) R, inductance and capacitance. Because R isn't frequency dependent and inductance doesn't contribute to losses when integrated over a full cycle, the only remaining parameter to juggle with is capacitance. @gyulasun and @lumen were mentioning earlier that possibility and @gyulasun even gave some links to that effect. Now, the problem is that there should be direct experimental evidence for the capacitance developing at the studied frequencies for the coil I'm using. Such, however, is lacking and all that can be said are only conjectures and assumptions.

Therefore, I'm intending to address this issue directly by taking the transformer apart and measuring the capacitance of the coil without the core at the various frequencies. Thus, I'm open to suggestions as to how all this can be done.

R is not frequency dependent. That's elementary!!! Trying to mislead again. Please try to be honest for once, I didn't say anything about R and frequency.

You stated:
'However, the real (dissipative) component of the impedance is not known to be frequency dependent and if claims are put forth that it is, these claims have to be sustained by experimental evidence. '

My response:
' Not true, the formula for impedance is Z = square root of R^2 + XL^2. XL has a frequency factor in its formula.'

The formula for XL = 2 Pi f L, where f is frequency. How can you not understand that frequency is part of this XL formula and is part of the Impedance formula.

If your transformer is of the typical EI lamination then it is simple to dismantle. Put the side of the E or I on a hard metal surface, then wack the other side lightly with a hammer. Continue to turn and wack until the enamel bonding starts to break loose. Then each E and I piece can be pulled out of the transformer until only the coil and bobbin is left.
