Problem 6 (15 points) The capacitance of a conducting spherical shell with radius a in a medium with 1 answer below »

Problem 6 (15 points) The capacitance of a conducting spherical shell with radius a in a medium with permittivity (shown in Figure (a) is given by C=4x E a . Using this result and the parallel or series combination of capacitors, find the capacitance of the structure shown in Figure (b), which is formed by placing a dielectric material with permittivity E between two conducting spherical shells with radii a and b (b>a). Hint: The structure in Figure (a) can be considered as a capacitor formed between two conducting spherical shells with radii a and o (a) (b)
