Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. The maximum rate of charge flow in a lightning bolt is about 20,000 C/s this lasts for 100 μs or less. 1.How much charge flows between the ground and the cloud in this time? (Q= ? C) 2.How many electrons flow during this time? (n_e = ? )
