Please write legibly.

A DC voltage V, is applied across a parallel plate capacitor. The space between the conducting plates are
filled with two different lossless dielectrics of thicknesses of d, and d2, permittivity &, and ɛ,respectively. The
area of each conducting plate is S.
a) Determine the capacitance
b) Determine the electric field intensity E inside the dielectrics.
c) Find the surface free charge density on the plates and at the interface of the dielectrics.
d) Repeat (b) and (c) for lossy dielectrics, i.e., assuming the conductivity of the two dielectrics is o, and o2.
