Vedclass · Answer

(C) Ohm's law states that the current flowing through a conductor is directly proportional to the potential difference across its ends,provided the temperature remains constant.Mathematically,this is expressed as $V \propto I$,which leads to $V = IR$,where $R$ is the resistance of the conductor.From this formula,we can also derive $R = \frac{V}{I}$ and $I = \frac{V}{R}$.Option $A$ $(R = \frac{V}{I})$ is a common representation of the definition of resistance derived from Ohm's law,but $V = IR$ is the standard form of the law.
