The earth is negatively charged, carrying 500,000 C of electric charge. This results in a 300 kV potential difference between the earth and the positively charged ionosphere. What is the capacitance of the earth–ionosphere system? If we assume that the bottom of the ionosphere is 60 km above the surface, what is the average electric field between the earth and the ionosphere?
