SUMMARY
The capacitance of three concentric spherical shells can be calculated using the formula C = Q/V, where V is derived from the electric field E = -gradV. For two shells, the capacitance is given by C = (4πε) / ((1/a) - (1/b)), where a and b are the radii of the inner and outer shells, respectively. To find the total capacitance of three shells, one must first calculate the voltage between the inner shells and then between the outer shells, adding the voltages as they are in series. This method effectively combines the capacitance contributions of each shell.
