Swimming during a storm figure shows a swimmer at distance D = 35.0 m from a lightning strike to the water, with current I = 78 kA. The water has resistivity 30 ?? ?? m, the width of the swimmer along a radial line from the strike is 0.70 m, and his resistance across that width is 4.00??O. Assume that the current spreads through the water over a hemisphere centered on the strike point. What is the current through the swimmer?
