A lightning bolt carrying 30,000 A lasts for 50 microseconds. If the lightning strikes an airplane flying at 20,000 feet, what is the charge deposited on the plane?

Solution:

Note that the “20000 feet” is irrelevant to this question.

I=30000A

t=50\mu s=50\times10^{-6}s

Q=(I)(T)

=(30000)(50\times10^{-6})

=1.5C
