Electrostatic Characteristics of Two Conducting Spheres in a Grounded Cylinder

An understanding of the electrostatic interaction between charged electrical conductors embedded in a grounded cylinder is quite useful in the design of compact pulse generators. We get the complete solution for capacitance between the two spheres and the capacitance between the sphere and the grounded cylinder in series form. The dependence of these capacitances on various geometrical parameters is very useful in the design phase of Marx generators where the stray capacitances play crucial roles.
