l=nAVde
actually ye expression hota h

volume of conductor of length l=Al
no.of electrons in the conductor =nAle
hence,charge is given on the conductor ,
q=nAle
time taken by the drift electrons moving in conductor with velocity v
t= l/Vd
acc.to definition of current
I=q/t
from above eq.
I=nAle/l/Vd
I=nAVde

nisha155: i hope it's very helpful 4 u
