Exercise 12

The space between two parallel conducting plates each having an area S is filled with an inhomogeneous ohmic medium whose conductivity varies linearly from 1 at one plate ( y = 0) to 2 at the other plate ( y = d ). A d-c voltage V o is applied across the plates. Determine
a) the total resistance between the plates, and
b) the surface charge densities on the plates.
