Exercise 16

A d-c voltage V o is applied across a parallel-plate capacitor of area S. The space between the conducting plates is filled with two different lossy dielectrics of thicknesses d 1 and d 2 , permitivities 1 and 2 , and conductivities 1 and 2 , respectively, as shown in Fig. 4-6. Determine
a) the current density between the plates,
b) the electric field intensities in both dielectrics, and
c) the equivalent R-C circuit between terminals a and b.
