Answer:
The current flowing through a conductor is given by the amount of charge passing through the cross section of the conductor in a given time.
I = Q/t
Where I - current flowing, Q - charge, t - time
charge can be calculated by the summation of number of charged particle flowing through the cross section multiplied by individual charge on the particle.
Q = n*e (e as here these are electons)
n = 6.25*(10^18) e = 1.6*(10^-19)
Q = {6.25*(10^18)} * {1.6*(10^-19)}
Q = 1 C
t = 5*60 = 300 sec
I = 1/300 = 3.33*(10^-3) A
I = 3.33 mA
