Taking:

L = u Nsqrd Area / l

Substituting: r/2l x Surface area solenoid = Area

Assuming spherical capacitor for the top end:

Capacitance = surface area sphere x e/R

Placing both of these into:

Freq. = 1 / 2 pi sqrt(LC)

Removing u and e from the radical as C

Placing an r in the numerator of the radical and pulling an r out of the radicals denominator. Gives us:

Frequency = C/ wire length x sqrt ( [2 (l sqrd) R r] / [ (Sa sphere x Sa solenoid)] )

Again the units of 1/s come from the velocity of light divided by the wire length. The rest of the expression has no units and can be thought of as a scaling factor.

We have been told numerous times that we have a pathological fixation on wire length. Hmmmm, is that so?
