In the return stroke of a typical lightning bolt, a current of `2.8 xx 10^(4)A` exists for `20 mu s`. How much charge is transferred in this event ?

Explanation

To solve the problem of how much charge is transferred during the return stroke of a lightning bolt, we can use the relationship between current, charge, and time. The formula we will use is:

\[ Q = I \times t \]

Where:
- \( Q \) is the charge transferred (in coulombs),
- \( I \) is the current (in amperes),
- \( t \) is the time (in seconds).
