Question

Need help with Parts 3 and 4, thanks! :)

Measurements made during severe electrical storms reveal that
lightning bolts can carry as much as 30 C of charge and can travel
between a cloud and the ground in time intervals of around 100 μs
(and sometimes even shorter). Potential differences have been
measured as high as 400 million volts.
1) What is the current in such a lightning strike? (Express your
answer to two significant figures.)

2) What is the resistance of the air during such a strike? (Express
your answer to two significant figures.)
