Re: Tesla Coil Formula

Jared,
What is the point of putting 2pi n/2 C/ wire in there
Once again you are trying to state that the length of wire wound on
the coil is the wavelength of the coil. This has been proven by
qualified people on this group that it is not true, it was a old
fasion belief at one time but progress has been made!
Maybe it's time to accept the fact that you are WRONG!
The correct form for this is:
Fo = c c is the speed of light
----------- = 300 million meters per second
wavelength
Why do you put n/2 in your equation?.
Wavelength is determined by the inductance of the coil, dealing with
tesla coils that is, and capacitance is a combination of the medhurst
capacitance and the top load.
The stuff on the right hand side of the equals sign is just the L C
resonance formula that everyone has seen along with your wire length
garbage. It is not a new formula. You expanded on the inductance
part, why not expand on the capacitance too ?
The correct standard form for the resonance formula that we are all
familiar with is:
Fo = 1
--------------------
2 pi sqrt (L C)
There are no new formula's that you posted! Why would you write an
equation like this anyway? Most equation have one variable to be
determined on the left hand side of the equals sign and the rest on
the right hand side.

Hi Bart:
We produce torroidal coils where the "natural" resonant frequency is
one wavelength. These coils are very good at producing sparks.
They obey the equation:
2pi n/2 C/ wire = 1/ sqrt ( (u/4pi) x [(Wire sqrd)/ 2n l] x Cap. )
"The application defines the discussion parameters."
We have built many different types of coils using the above equation.
The equation does qualify as a Tesla coil formula. The topic is about
Tesla Coil Formula's.

Hi Matt:
We have not experimented with bifilar windings, but it does sound
interesting. Right now I am winding a spherical inductor to see how it
performs as a half wave, or at least I was winding it untill I ran out
of wire.
All systems will have 3/4, 1, 1.5, wave lengths as based from the
reference operating frequency. But, they will not operate well at
those frequency's as compared to the "natural" system resonant
frequency "for the purpose of producing sparks". The very minute the
coil is affected by outside influence, the coil is no longer 1/4 wave
wire length, and that's just nature taking it's natural course.
Sparks are mostly what this list is about. If a system other than
that is to be discussed, then we must certainly differentiate the
application. I think possibly this is the defining reason for so much
disagreement on these type of topics.
The application defines the discussion parameters.
Thanks for your comments.
Take care,
Bart
