The legend that Benjamin Franklin flew a kite as a storm approached is only a legend - he was neither stupid nor suicidal. Suppose a kite string of radius 2.00 mm extends directly upward by 0.620 km and is coated with a 0.500 mm layer of water having resistivity 150 ·m. If the potential difference between the two ends of the string is 120 MV, what is the current through the water layer?
