capacitor (1 nanofarad) 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 3 x 1018 2; on a humid day, the resistance is 6 × 10° 2. How long will i take the capacitor voltage to dissipate to half its original value on each day? On the dry day, it will take seconds.
