A current of 10A exists in a conductor. Assuming that this is current is entirely due to the flow of electrons (a) find the number of electrons crossing the area of cross section per second,(b) if such a current is maintained for one hour,find the net flow of charge

As we know relation between current and drift velocity
I. e I = v
d
ena
where I = current
v
d
=drift velocity
e = electron
n = no of electrons per unit volume
a =area of cross section
10=9×10
