Problem 38

A parallel-plate capacitor is being charged. The capacitor consists of a pair of identical circular parallel plates that each have a radius and a separation distance (a) Show that the displacement current in the capacitor gap has the same value as the conduction current in the capacitor leads. (b) What is the direction of the Poynting vector in the region between the capacitor plates? (c) Find an expression for the Poynting vector in this region and show that its flux into the region between the plates is equal to the rate of change of the energy stored in the capacitor.
