Vedclass · Answer

(A) Ohm's law states that the current $I$ flowing through a conductor is directly proportional to the potential difference $V$ applied across its ends,provided the physical conditions (like temperature) remain constant.Mathematically,this is expressed as $V = IR$,where $R$ is the resistance of the conductor.Since $R$ is constant for an ohmic material,the equation $V = IR$ represents a linear relationship.Therefore,the graph of $V$ versus $I$ is a straight line passing through the origin $(0,0)$.
