Question

The $V$-$I$ graphs for a conductor at two different temperatures $T_1$ and $T_2$ are shown in figure. The steeper slope corresponds to $T_1$. Write the relation between $T_1$ and $T_2$.

Accepted Answer

Slope of $V$-$I$ graph = resistance $R = V/I$.
Steeper slope means higher $R$, which in metals means higher temperature.
$$	herefore T_1 > T_2$$
