A capacitor is formed of two concentric spherical conducting shells ofradii a and b . If the medium between the spherical shells has a dielectric constant K_(1) from radius a to r and K_(2) from radius r to b , find the capacitance of such a spherical capacitor shown in figure.

calculate the effective capacitance of the connection if a dielectric material of dielectric constant K is filled in between the plates as shown in the adjoining figure (n).

The space between parallel plate capacitors is filled with four dielectrics of equal dimensions but of dielectric constants K_(1), K_(2), K_(3)andK_(4) respectively. If K is the dielectric constant of a single dielectric that must be filled between capacitor plates to have the same capacitance between A and B. Then we must have
