If I have a coil of diameter D (in mm), using wire that is d mm in diameter, having N turns over a total height of L mm, assuming that it is just a single layer, and has an air core, is it possible to calculate what the self resonance frequency should be (approximately) of such a coil? If so, what would the formula for the frequency be? If not, what additional information needs to be known?
To dispel any concerns about doing someone's homework for them in advance, be assured that this is not a homework question. I'm just curious how this kind of thing can be calculated. Thanks.
So... for clarification purposes I have the following parameters:
1) Diameter of the coil (D) in mm 2) Diameter of the wire (d) in mm 3) Overall height of the coil (L) in mm 4) Number of turns (N)
I also know the material in the conductor of the wire, although I do not think that would be relevant to solving the problem unless the material was not a good conductor.
One thing we categorically cannot assume is that I will have any way to measure any properties of the coil with tools such as a meter or scope... I am asking how to calculate this on paper only.
