Show that the capacitance of spherical capacitor is more than that of a spherical conductor.

Define capacitance of a capacitor?

A spherical capacitor consists of two concentric spherical conductors, held in position by suitable insulating supports (Fig. 2.36). Show that the capacitance of a spherical capacitor is given by C = (4piepsilon_0r_1r_2)/((r_1)-(r_2)) where r_1 and r_2 are the radii of outer and inner spheres, respectively.:

Calculate the capacitance of a spherical capacitor if the diameter of inner sphere is 0.2m and that of the outer sphere is 0.3m, the space between them being filled with a liquid having dielectric constant 20

The stratosphere acts as a conducting layer ofr the earth. If the stratosphere extends beyond 50 km from the surface of earth, then calculate the capacitance of the spherical capacitor formed between stratosphere and earth's surface. Take radius of earth as 6,400 km.

The capacitance of a parallel plate capacitor increases with

On what factors the capacitance of a capacitor depends?

Show that the capacitance of an insulated spherical conductor is directly proportional to the radius of the spherical conductor.

What is value of capacitance of earth when it is considered to be spherical conductor?
