SUMMARY
The problem involves calculating the current during a lightning strike where 2.5 coulombs (C) of charge flows to the ground in 0.020 milliseconds (ms). The correct calculation for current is achieved using the formula I = Q/t, where I is current, Q is charge, and t is time. The user initially miscalculated the time as 0.0002 seconds instead of the correct 0.00002 seconds. The accurate current during the lightning strike is 125,000 amperes (A).
