During lightning strikes from a cloud to the ground, currents as high as 2.50×10^4 amps can occur and last for about 40.0 microseconds . how much charge is transferred from the cloud to the earth during such a strike?

1 C

Explanation:

The intensity of electric current is defined as

where

I is the current

q is the amount of charge transferred

t is the time interval during which the charge is transferred

For the lightning in this problem, we have

is the current

is the time interval

Solving the formula for q, we find the amount of charge transferred:
