Question

how have adivasis become marginalised

Answer 1

Explanation:

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}}}

i=neAVd
