(a) How can you describe dielectric material? Explain and draw the energy band diagram for dielectrics. (b) Think that an electric field was applied to a dielectric material. According to the type of dielectric material, which and how many polarization mechanisms can be observed? Explain item by item. (c) Determine the dipole moment for the following charge distrubutions:
1.5\mu C
each at the points
(0,3)
and
(0,5)
, where the coordinate numbers are given in meter and in cartesian coordinate system as (
x,y
).
