The current - voltage graphs for a given metallic wire at two different temperatures `T_1 and T_2` are shown in the figure.

The temperature `T_2` is greater than `T_1`.

Text Solution

Verified by Experts

For a given voltage, current is more in case of `T_1`.
Since, `V=IR`
`:. R = V/I`

Resistance is less in case of `T_1 and more in T_2`.
