A spherical capacitor, constructed of two concentric conducting spheres, is filled with an insulating material with a relative permittivity, εr, equal to 4. The inner sphere is held at a potential of 0 volts, and the outer sphere is held at a potential of V0 volts. The inner sphere has a radius of ‘a’, and the outer sphere, a radius of ‘b’.
