The visible discharge of electricity occurs when a region of a cloud acquires an excess electrical charge (either positive or negative) that is sufficient to break down the resistance of air.
Current is a measure of the flow of electric charge over time.
It is defined as
where q = Charge
t = Time
I = Current
Calculation:
Given:
q = 25 C
I = 2.5 kA
t = 10 milliseconds
