(4) [5 points] A capacitor consists of two round metal plates with diameter 2 centimeters. The plates are held apart by a thin layer of plastic, 0.2 mm thick. The material properties of the plastic are as follows: the resistivity is 2 x 1011 - m; the dielectric constant is 2.3. Because the plastic is not very thick and not that good an insulator, this capacitor is subject to leakage current. This leakage current is current that will flow between the plates through the plastic. if we charge the capacitor and disconnect it from the voltage source, it will eventually discharge like an RC circuit. (a) What is the capacitance of this capacitor? (d) What is the resistance of this capacitor? (e) How long will it take for 99% of the charge to leak through the plastic
