A person of height "h" is standing a distance "d" from a tree. As a lightning bolt of current I=5000A travels down the tree, some of the current jumps through the air to the person and travels through him to ground. The resistance of the person is negligible compared to the resistance of air. The rest of the current travels in air along the tree trunk. If d/h = 0.400 what is the current through the person?
