my intution tells me that cap size and inductance is not a linear
relationship. especially when you consider the outer turns of a conical or
flat spiral coil...each consecutive turns affords more inductance than the
aside from reduced sprak gap losses from more primary turns, are there any
other areas that contribute to longer sparks associated with a larger
primary? i had originally read that more turns in the primary allowed more
effecient transfer of energy between the coils, or something about superior
coupling (12-15 turns being the "sweet spot").
