第一題 圖在上面的連結@@
An emf V is applied across a parallel-pate capacitor of area S.
the space between the conducting plates is filled with two different
lossy dielectrics of permittivities (ε_1) and (ε_2) ,
and conductivities (σ_1) and (σ_2) respectively.
These two dielectrics have the same thickness d.
(1)Find the current density between the plates.
(2)Determine the electric field intensities in both dielectrics.
(3)Determine the surface charge densities on the plates and at the interface
of the dielectrics.
(Note: neglecting fringing effect at the edges of the plates) (20%)
