in 1 of the question of h c verma numbered61: "A spherical capacitor is made of two conducting spherical shells of radii 'a' and 'b'. the space between the shells is filled with a dielectric of dielectric constant 'k' upto a radius 'c'. calculate the capacitance?" i hav refered al possible solutions of h c verma and also askd as many colleagues and teachers as possible but i couldnt understand why we take the two capacitors in parallel thought i feel it must b taken in series so as to get answer y do we take in parallel plz answer
