Vedclass · Answer

(A) The slope of the $V-I$ graph represents the resistance $R$ of the conductor,as $R = V/I$.From the given figure,the slope of the line corresponding to temperature $T_1$ is greater than the slope of the line corresponding to temperature $T_2$.Therefore,$R_{T_1} > R_{T_2}$.For a metallic conductor,the resistance increases with an increase in temperature.Since the resistance at $T_1$ is greater than the resistance at $T_2$,it follows that $T_1 > T_2$.

The voltage $V$ and current $I$ graph for a conductor at two different temperatures $T_1$ and $T_2$ are shown in the figure. The relation between $T_1$ and $T_2$ is
