Question

solve the question
derive I=nAeVd

Answer 1

consider a conductor length L and cross section A.where electric field E is applied across it.the e are the drifted opposite to the electric field.
Let Vd is the drift velocity of electrons.

Volume of conductor (V) =AL
Let n is the number 9f electrons per unit volume.
Then, number of electrons in volume V = nAL

Now, we know,
charge of one electron = e
charge of whole electrons(q) = neAL

q = neAL

current = charge/time
= neAL/t
=neA(L/t)
= neAVd. {Vd = L/t }

$\boxed{\boxed{\bold{i=neAVd}}}$
