[TCML] more air core stuff



Just running some numbers.. say you have 1000 turns of AWG22 wire on a 20" diameter form (the winding would be about 1x1" in cross section). Pretty close to 1 Henry

OK, that's about a mile of wire (5235 ft), and will have a DC resistance of 87 ohms and be about 10 pounds of wire.

You can see why iron cores might be popular (e.g. a LOT less wire, which would reduce the resistance and the copper weight)

In a TC application, say you're using it as a charging choke with an rms current of 1A.. that's about 90W you're going to be dissipating. On a 10 kW coil, that's 1%
