Displacement Current in a Dielectric Suppose that the parallel plates in Fig. 29.23 have an area of 3.00 cm2 and are separated by a 2.50-mm-thick sheet of dielectric that completely fills the volume between the plates, the dielectric has dielectric constant 4.70. (You can ignore fringing effects.) At a certain instant, the potential difference between the plates is 120 V and the conduction current ic equals 6.00mA. At this instant, what are?
(a) The charge q on each plate;
(b) The rate of change of charge on the plates;
(c) The displacement current in the dielectric?
