Question

Explain ohms laws with the help of a graph between potential difference [v] and current [i] flow through cicuit

Answer 1

"when the thermal state of the conductor is not changed the potential difference across the two terminals directly proportional to the applied electric current "

Answer 2

The current through a metallic elements is proportional to the potential difference applied between its end, provided the temperature remains constant.
                    V ∝ I
                    V = IR                                  R is constant of proportionality
                                                         R is known as resistivity
                    V/I = R
