Sorry, i posted this same Q in the wrong location. i dont know how to delete it. i attached a couple pics. just wondering if this would make a good top load for my tesla coil. also, how do i calculate its capactitance? TY

I'd be inclined to use just one,
use the primary former to support it
and make the winding end somewhere around the level of the bottom of the topload (?)
- could look good
- easy support of the topload
- more than half of the capacitance of a pair
- about the same breakout voltage as a pair
- leaves a spare for a twinTC or wireless power transfer etc.
As a first guess you could estimate the capacitance as (my guess) 3/4 the capacitance of a sphere of the same diameter
(C = r / 9e9 )(C=pF, r=radius=m)

Is there a way to measure the capacitance of a top load with a digital capacitance meter?
