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`.

Options

A. `T_1 gt T_2`
B. `T_1 lt T_2`
C. `T_1=T_2`
D. `T_1` is greater or less than `T_2` depending on whether the resistance R of the wire is greater or less than the ratio `V/I`

Answer

B
