Answer
V-I graph of a conductor at two different temperatures T1 and T2 is shown below:
Figure shows two straight lines A and B on the V-I graph for a conductor at two different temperatures T1 and T2 (T1 > T2) respectively.
The straight line A is more steeper than the line B because the resistance of conductor is more at high temperature T1 than at low temperature T2
