Consider a spherical capacitor
made of the 3 linear dielectrics: 1 for a < r < b, 2 for b
< r < c, and 3 for c < r < d. There
is conducting material covering the inner surface (r=a) and the
outer surface (r=d). What is
the capacitance of this device? You can assume that there is total
charge Q and -Q built up on
each of the inner and outer conducting surfaces and that there is a
potential di erence V between
the conductors.
