Spherical Capacitors

A spherical capacitor consists of two concentric spherical shells of outer radius r1 and inner radius r2, held in position by suitable insulating supports. calculate the capacitance of this spherical capacitor.

A spherical capacitor consists of two concentric spherical conductors, held in position by suitable insulating supports. Show that the capacitance of this spherical capacitor is given by C = (4pi in_(0) r_(1) r_(2))/(r_(1) - r_(2)) , Where r_(1) and r_(2) are radial of outer and inner spheres respectively.

A spherical capacitor consists of two concentric spherical conductors, held in position by suitable insulating supports (Fig). Show that the capacitance of a spherical capacitor is given by C=(4piepsi_0r_1r_2)/(r_1-r_2) where r_1 and r_2 are the radii of outer and inner spheres , respectively.
