Capacitance and inductance of cylindrical shell

AI Thread Summary
The discussion focuses on calculating the capacitance and inductance of a cylindrical shell with a dielectric filling and a small gap. The geometry is described as a split ring rather than a perfect circle, complicating the calculations. Reference is made to Smythe's "Static and Dynamic Electricity" for solutions to similar cylindrical geometry problems. The relationship between inductance per unit length (L) and capacitance per unit length (C) is highlighted, with a specific formula provided. This information is essential for solving the capacitance and inductance issues presented.

i am having trouble with finding inductance and capacitance of a cylindrical shell with gap.

say inner radius is a, outer radius is b, and filling dielectric between a and b,

and its not a exact circle which have a small gap say d. its like a split ring but only one shell.

How can i find C and F?

Smythe "Static and Dynamic Electricity" (third edition) has solutions for many difficult cylindrical geometry capacitance and inductance problems, including off-center geometries.

For these problems, if L is the inductance per unit length, and C is the capacitance per unit length, L and C are related by

LC = εε0μμ0 = 1.11 x 10-17 εμ Farad-Henrys/meter2

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
