My name is Jim Watson. I am a student (non-traditional) at the University of West Florida in Pensacola, Florida; in the Electrical Engineering Technology program. "Non-traditional" is a euphamism which means that I am a bit older than the normal student. I am writing a paper on Nikola Tesla and the Wireless Transmission of Power; I am designing and building a Tesla Coil as part of the same project.
The equation regarding the capacitance of a toroid. the one contributed by Bert Pool, is not entirely clear to me. There is a numer 2 in the numerator of the radicand that I can not place with 100% certianty; this is because the formula has always arrived in a slightly jumbled form, and I have to reconstruct it.
The two appears to square 2pi; it appears to be (2pi)^2. Is this correct? The remainder of the equation is very clear. I would also appreciate any comments on the origin of this formula.
