Vedclass · Answer

(A) The slope of the $V-I$ graph represents the resistance $R$ of the conductor,as $R = \frac{V}{I}$.From the given graph,the slope for temperature $T_1$ is greater than the slope for temperature $T_2$.Therefore,$R_1 > R_2$.For a metallic conductor,the resistance increases with an increase in temperature.Since $R_1 > R_2$,it follows that $T_1 > T_2$.

The $V-I$ graph for a conductor at two different temperatures $T_1$ and $T_2$ is shown. The relationship between $T_1$ and $T_2$ is:
