Re: AC coil resistance equation



There's been a lot of stuff here lately on calculating or measuring the
UNLOADED Q of a TC.  I think this is mostly a waste of time, although I
do it myself for amusement.  The real LOADED Q of any decent coil will
be very much lower than the UNLOADED, or the efficiency would be very
low.  Best way to estimate Q is to try to measure the decay of each
output impulse and calculate the logarithmic decrement, which as I
recall is PI/Q.
