Answer:
Step-by-step explanation:
Given that,
Charge through a wire is 
 Q = 4000C
Time for charge to pass through the wire is
t = 50seconds
Then,
Current through the wire is the rate of charge passing through the wire
Q = it
Where 
Q is charge.
I is current 
t is time taken
Therefore,
I = Q / t
I = 4000 / 50
I = 80 Amps
