online calculator or formula applicable to gauge less than 50 SWG ?
"Nutcase Kook"
All online and my tables stop at 50 SWG. I don't know if the standard
copper
resistivity formula breaks down over/less than 50 SWG. Wire in question ,
measured optically to about 0.05 mm diameter as too fine to mike up. About
19.7 ohm per metre but what is that in AWG or SWG ?
** Last time I dealt with fine enamelled wire like, that it was from the
high impedance (output end ) transducer of an Accutronics reverb unit.
But the finest I have seen is on the coil of an AKG D19 ( 200 ohms) mic
capsule - about 0.03 mm.
The D19 diaphragm was sold as a spare part and used in other mics, like the
original D12.
