As mentioned earlier capacitance occurs when there is a separation between the two plates. So for constructing a spherical capacitor we take a hollow sphere such that the inner surface is positively charged and the outer surface of the sphere is negatively charged. The inner radius of the sphere is r and the outer radius is given by R.
In a spherical capacitor you have two concentric conductor spheres. According to Gauss law, if the inner shell (radius r 1) has a charge Q, the electric field in the dielectric at a radius r ≧ r 1, will only be determined by this charge, there is no influence of a charge at the radius r 2 of the outer shell.
Discharging of a capacitor. As mentioned earlier capacitance occurs when there is a separation between the two plates. So for constructing a spherical capacitor we take a hollow sphere such that the inner surface is positively charged and the outer surface of the sphere is negatively charged.
A spherical capacitor consists of a solid or hollow spherical conductor, surrounded by another hollow concentric spherical of different radius. A spherical capacitor formula is given below: Where, C = Capacitance Q = Charge V = Voltage r 1 = inner radius r 2 = outer radius ε 0 = Permittivity (8.85 x 10 -12 F/m)
The capacitance for spherical or cylindrical conductors can be obtained by evaluating the voltage difference between the conductors for a given charge on each. By applying Gauss' law to an charged conducting sphere, the electric field outside it is found to be Does an isolated charged sphere have capacitance? Isolated Sphere Capacitor?
