Re: Secondary Theory (Was Bipolar Coil)-Heretical view


	In my post, I accidently said secondary when I should have said primary.
I meant to say that the secondary resistance, as long as it is reasonable,
does not have a great effect on the system.  However, primary resistance is
VERY important and must be minimized with all reasonable efforts.  I think
we agree, but I just typed too fast...
