Question

3. A parallel plate capacitor filled with a dielectric (k=ko) is fully charged to a value Qo. Find an expression for the time dependence of the charge decay on the capacitor plates under the following conditions: a) Apply one of Maxwell’s Equations for statics, ∮ ? ∙ ?l= 0, to the following ‘circuit’: A perfect capacitor is connected, by a perfectly conducting wire, to a cylinder with conductivity g. The area of the plates and cross section of the cylinder are the same; likewise, the distance between the plates is the same as the length of the cylinder.
