Re: AC Resistance of wires - was 8 kHz Tesla Coil



Original poster: Jim Lux <jimlux@xxxxxxxxxxxxx>



5% is difficult to even see in an oscilloscope, and the precise value
for wr/sd=2 looks a bit "out of the curve". Possibly wrong.
Consider also that for Tesla coils, at least in secondary coils, the
proximity effect is very significant. And also, the operation is
not at sinusoidal steady state, and so the use of a fixed value
for skin depth is an approximation only.


An excellent point. Roll out the FDTD simulators!
