Re: Ah, thanks.

Note that within the text, they had calculated a rise in resistance of 34% as a result of skin effect at 20Khz and #12awg. Note that the measurements at 20Khz did not confirm at all the predicted results of the exponential equation...the measurements were pretty close to flat at that point.

It can be concluded from their measurements of #12 alone, that there is a problem with using the exponential equation for skin depth. The equation predicts on the shallow side of actual.

It is also quite difficult getting accurate readings in that realm, as I don't know to what extent Gene zero'd out the meter for each range....the article doesn't specifically state that, and that is where I would see the most measurement error. I would have to review the setup and procedure for measurement accuracy to be confident in the readings.

You are concluding that there is significant skinning at 20K, but yet the graphs don't really show much in the way of effect at 20K. Stealth premier II and #10 show some rise there, but certainly not much. And if you look at their absolute numbers, they are very low resistance numbers, indicative of lots of conductor, not smaller wires as you are alluding to.

Your statement is not supported by their results.

Oh, btw...long time no speak...How are you doing, Tom?

Cheers, John
