let no. of electrons per unit volume=n
charge on an atom=e
no.of electrons in length l of the conductor=n×volume of conductor=nAl
total charge contained in the conductor is
q=neAl
all the electrons which enter the conductor at the right end will pass through the left end of the conductor in time,
t=distance/velocity
=l/vd
therefore,current,
I=q/t=enAl/(l/vd)
=> I=neAvd

Self-inductance is the tendency of a coil to resist changes in current in itself. Whenever current changes through a coil, they induce an EMF, which is proportional to the rate of change of current through .
