In what appears to be a single lightning bolt, there are typically several distinct strokes over the same path, each lasting on the order of 10-4 s, with an interval of about 0.05 s between them. The duration of the several strokes is about 0.20 s. Thus, although the peak current may reach a maximum of 20,000 A, the average current over the 0.20 s is much less-typically about 120 A upward. Find the charge transferred to one point on the earth's surface during a typical 0.20 s discharge.
