Subtopic: Variation of Resistance with Temperature

The voltage V and current I graph for a conductor at two different temperatures T1 and T2 are shown in the figure. The relation between T1 and T2 is :- Image related to
T1 > T2
T1 ≈ T2
T1 = T2
T1 < T2

Solution:

Slope of V-I graph represents Resistance. So R1>R2
