What average current is required to vaporize the water

Reference no: EM13500553

The rain-soaked shoes of a person 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 ·m, length 12.0 cm, and vertical cross-sectional area 1.3 10-4 m2, what average current is required to vaporize the water?
