Re: 8 kHz Tesla Coil

Hi Bart,

Maybe doing this would be better than nothing. At least for close wound coils, the assumption may be close enough and relative comparisons would be valuable perhaps.

In additions to Rdc and skin depth, having estimated Rac, and estimated Q (based on Rac, Les, and Ces) would be good additions for JAVATC.

BTW, I dont understand why you added Rdc to Rac to come up with Reff. This doesn't sound right. Seems like Rac is Reff and is calculated from the effective cross sectional area of the wire based on skin depth (and perhaps an estimate of proximity effects thrown in). As freq -> 0, Rac becomes Rdc and is the effective R.

That would certainly throw you in the ball park. We could use this or similar as a generic factor for now, but it's one of those areas that needs some time spent on it. Only then can we really identify a high and low Q design.
