Consider a coaxial capacitor having inner radius a, outer radius b, unit length, and filled with a material with a dielectric, εr.
Compare this to a parallel plate capacitor having a plate width w, plate sepparation d, filled with the same dielectric material, and having unit length.
Express the ratio b/a in terms of ration d/w, such that the same structures will store the same energy for a given applied voltage.
