The rain-soaked shoes of a man may explode if ground current from nearby lightning vaporizes the water. The sudden conversion of water to water vapor causes a dramatic expansion that can rip apart shoes. Water has density 1000 kg/m³ and requires 2256 kJ/kg to be vaporized. If horizontal current lasts 2.00 ms and encounters water with resistivity 120 Ω·m, length 12.0 centimeter, and vertical cross-sectional area 1.3 x 10^-4 m², compute what average current is required to vaporize the water?
