The graph between $V$ and $I$ for a conductor is a straight line passing through the origin.(a) Which law is illustrated by such a graph ?(b) What should remain constant in a statement of this law ?


(a) Ohm's law is represented through $V$ and $I$ graph for a conductor. Since the graph is a straight line, we can conclude that $V \propto I$

(b) Temperature and other physical conditions must be constant for the law to be valid.
