Capacitance and inductance of cylindrical shell

Click For Summary
SUMMARY

The discussion focuses on calculating the capacitance (C) and inductance (L) of a cylindrical shell with a dielectric filling and a small gap. The inner radius is denoted as 'a', the outer radius as 'b', and the gap as 'd'. The reference text "Static and Dynamic Electricity" by Smythe provides solutions for complex cylindrical geometries, including those with off-center configurations. The relationship between inductance and capacitance is defined by the equation LC = εε0μμ0 = 1.11 x 10-17 εμ Farad-Henrys/meter2.

PREREQUISITES

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
