A flash of lightning transfers
1.5 x 10^9 Joules of energy through a potential difference of 5.0 x 10^7 Volts between a cloud and the ground. Calculate the quantity of charge transferred in the lightning bolt.
How many electrons were transferred?
Does this get easier? I hope so.
physics 30 -
q =Energy/Δφ = 1.5•10^9 /5•10^7 =30 C,
N =q/e = 30/1.6•10^-19 = 1.87•10^10.
