Obtain what average current is required to vaporize water

Reference no: EM13665488

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 millisecond and encounters water with resistivity 145 ohm•m, length 12.0 centimeter, and vertical cross sectional area 1.5 x 10-⁴m², Find what average current is required to vaporize the water?
