Answer Posted / elumalai
According to Sir George Simon Ohm"when the current flows
through the conductor, the current is directly proportional
to potential difference between the two ends of the
conductor". ie
V=IR
Where R is the proportionality constant known as resistance
of the conductor. ie
R=$L/a
where $ is the resistivity of the material,
L is the length of the conductor,
a is the Area of cross section.
