Question

82. ••• Lightning bolts can carry as much as 30 C of charge and can travel between a cloud and the ground in around 100 μs. Potential differences have been measured as high as 400 million volts. (a) What is the average current in such a lightning strike? How does it compare with typical household currents? (b) What is the resistance of the air during such a strike? (c) How much energy is transferred during such a strike? (d) What mass of water at 100°C could the lightning bolt evaporate? Example 18-9

Answer:

The average current is 300,000 A =0.3 MA

The resistance is = 1333.33 =1.33 K ohm

The energy translated is =
`1.2*10^(10) J` =
`1.2*10^(5) GJ`

The mass of water at 100°C the lightening bolt can evaporate is
`5309.73kg`
