Question

deduction of Ohm's Law

Answer 1

Ohm's law and its derivation. Mobility of electron (ue) is defined as the drift velocity of electron per unit electric field applied. Where R is known as resistance of the conductor . ... The variation between potential difference (V) and current (I) through a conductor is a straight line.

Answer 2

Statement __Ohm s law states that the current l flowing through a conductor is directly proportional to the potential difference V across the ends of the conductor provided physical conditions of the conductor such as temperature mechanical strain acceptor are kept constant letters laV or V=IR=a constant
where l is known as resistance of the conductor it depends upon the length shape and nature of the material of the conductor the variation between potential difference v and current I through a conductor is a straight line .

deduction of Ohm's Law :
As drift velocity is given by Vd= eEt/m
but electric field across the conductor of length L is E=V/l
thus Vd = eV/ml
also, I=Anevd
by putting value of V D in equation of a (equation of relation of the current and drift velocity )we get
I=Ane(eV/ml)
