A parallel-plate capacitor has plates of 10 cm^2 area separated by a 0.10mm layer of glass insulation with resistivity rho = 1.2x10^13 omega*m and dielectric constant k= 5.6. Because of the finite resistivity, current can leak through the insulation.
How do I Show that it depends only on the properties of the insulating material and not on its dimensions?
The Attempt at a Solution
I found the time constant for this capacitor to discharge through its insulation. T= 590s
