A 10^-8-F capacitor (10 nanofarads) is charged to 50 V and then disconnected. One can model the charge leakage of the capacitor with a RC circuit with no voltage source and the resistance of the air between the capacitor plates. On a cold dry day, the resistance of the air gap is ; on a humid day, the resistance is How long will it take the capacitor voltage to dissipate to half its original value on each day?
