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 micros
econds . How much charge is transferred from the cloud to the earth during such a strike?

Answer:
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 current
 is the time interval
 is the time interval
Solving the formula for q, we find the amount of charge transferred:

Answer:0.114 C
Explanation:
Given
Total 4.7 C is distributed in two spheres
Let  and
 and  be the charges such that
 be the charges such that

and Force between charge particles is given by



put the value of 




thus 
 
        
             
        
        
        
The flow of electricity in a certain path is the circuit.
