Bart -

My graph was strictly a one toroid only graph. Note that all these space
capacitances are reduced when the toroid is placed on the secondary coil.
Just how much reduction can only be found by actual tests while the TC is
operating. Or you can use the JHCTES Ver 3.1/3.2 programs to find the actual
capacitance if you know the operating frequency.

Yes John, but does you graph indicate the same compacitance as was posted
for overlapped toroids? I'm guessing
it doesn't because Bert Pool's equation calc'd exactly as was posted on
these toroids.
