I am wondering how to different dielectric material with different relative permittivity behave when put together. Say i have two concentric sphere and the space between them is filled with a dielectric of relative permittivity A from the outer surface of the inner sphere to the mid point between the inner and outer sphere and another dielectric of relative permittivity B fills the remaining space between the spheres. In such case, how do they behave and affect the capacitance of such a capacitor?
