I would like to calculate theoretically the capacitance of a bearing with metallic rings and ceramic spheres (see http://en.wikipedia.org/wiki/Rolling-element_bearing.(adsbygoogle = window.adsbygoogle || []).push({});

The expression for a cylindrical capacitor is: (2*pi*eps0*l)/(lnb/a).

However, when adding some spherical balls inside the cylinder, how should I proceed?

Thank u,

logic
