Hint:The rule was named after German physicist Georg Ohm, who reported measurements of applied voltage and current via basic electrical circuits comprising varying lengths of wire in a book published in 1827. Ohm's experimental results were described by a somewhat more complicated equation than the current one above.

$I = \dfrac{V}{R}$
where $I$ is the current through the conductor in amperes, $V$ is the voltage measured across the conductor in volts, and R is the conductor's resistance in ohms. Ohm's law indicates that the $R$ in this relationship remains constant regardless of the current.
Non-ohmic materials, on the other hand, do not follow Ohm's law.When a conductor is kept at a constant temperature, Ohm's Law states that the current flowing through it is proportional to the voltage across it. This means that if we plot voltage on the x-axis and current on the y-axis of a graph, the result will be a straight line. The resistance of the conductor is linked to the gradient of the straight-line graph as $\dfrac{I}{V} = \dfrac{1}{R}.$
