8.2: Capacitors and Capacitance

A spherical capacitor is another set of conductors whose capacitance can be easily determined (Figure (PageIndex{5})). It consists of two concentric conducting spherical shells of radii (R_1) (inner shell) and (R_2) (outer shell). The shells are given equal and opposite charges (+Q) and (-Q), respectively. From symmetry, the
