The earth can be considered as a single-conductor capacitor . It can also be considered in combination with a charged layer of the atmosphere, the ionosphere, as a spherical capacitor with two plates, the surface of the earth being the negative plate. The ionosphere is at a level of about 70 km, and the potential difference between earth and ionosphere is about 350,000 V. Calculate: (a) The capacitance of this system; (b) The total charge on the capacitor; (c) The energy stored in the system.
