Question

The V-I graphs of a metallic conductor at
temperatures T, and T, are shown in figure.
We may conclude:
(a) T1 =T2

(b) T1 > T2
c)T1<T2
(d) T1and T2 cannot be compared​

Answer 1

T1<T2

This and may help you

Answer 2

the resistance of conductor on T1 is R1 and T2 is R2.

then by the graph, on T1, V is greater I is less and on T2, V is less and I greater.

so, R1 > R2

ans R is proportional to T

so, T1 > T2
