Wouldn't all of the stray inductance adversely affect the peak current?

Hi Jim,

As Jim Lux and Antonio explained, it's likely not
a big deal, but it "is" worth measuring,
especially on a large MMC as you are building.
Keep in mind that the inductance is relative. If
you have a really small coil that uses little
primary L, then the concern is greater. But if it
is a normal size coil (3" secondary or larger),
there's likely no worry's. I have found through
both modeling and experimentation, that lead
inductance is an issue when the primary is small
(for a tiny coil) and the MMC inductance may also be worth taking a look at.

I'm glad you brought this point up. It's
something I haven't measured and it was never a
concern before (until I started building little tiny coils).

Take care,
Bart
