This logically suggests that when you talk about an "equivalent capacitance" to a battery that you mean a capacitor that stores or can deliver the same energy as the example battery. In theoretical terms your calculation is correct for an idealised battery (constant voltage throughout discharge, defined mAh capacity) and an idealised capacitor.
Using the recent advances in the asymptotic analysis of Fredholm integral equations of the second kind with finite support, here we study the one governing the circular capacitor, known as the Love equation. We find analytically many subleading terms in the capacitance at small separations.
For a capacitor, it denotes the ratio between the charge on one of the plates and the potential difference between them. The capacitance purely depends on the geometry. The standard simplification in the textbooks is a parallel plate capacitor in a vacuum with the characteristic plate size much larger than their separation.
The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage V across its plates. In other words, capacitance is the largest amount of charge per volt that can be stored on the device: C = Q V
Most of the time, a dielectric is used between the two plates. When battery terminals are connected to an initially uncharged capacitor, the battery potential moves a small amount of charge of magnitude Q from the positive plate to the negative plate. The capacitor remains neutral overall, but with charges + Q and − Q residing on opposite plates.
Our goal is to find the capacitance of a circular capacitor that consists of two thin coaxial conducting disks of unit ra-dius at the separation κ. The disks are held at equal potentials in the absolute value, ±V0/2, which guarantees equal charges on the two surfaces, ±Q. By the definition, the capacitance is given by C Q /V0.
