Electric current in a conductor , i = - n e V A
Where n = no. of charges , e = Charge , V = Drift speed and A = Area of cross-Section.
When Potential Difference applied across a conductor , An electric gets setup across a conductor, due to which electrons start drifting with the speed of 10 raised to the power of -4 m/s...Which is a very small speed though its impact is large as the n is large...
So electrons drift with the order of 10^-4 m/s in a conductor...
