Hi Rod,

You probably shouldn't bother trying to measure the TC output with the divider
that you mention above, as those 'useless theories' predict that the +/- 200kV
margin will result in a measurement error of over 100%, for standard size coils.

It's true that a rigorous theoretical treatment is not necessary to support a
satisfying Tesla Coil hobby, unless the builder has a curious mind and a need
to understand how the crazy thing works.  There are plenty of 'rules-of-thumb'
for TC construction floating around nowadays -- the fruits of countless man-years 
of trial and error, and dumpsters full of destroyed or obsoleted equipment.
  
Theoretical modeling is frustratingly hard work, which is why most people avoid 
it like the plague!  It becomes more attractive however, when human lives or 
large sums of money are at stake, and there might not be a second chance.

At the least, a basic theoretical background is useful for detecting and avoiding 
the ever-present 'fringe science' menace, or even just simple mistakes.
