Question

# The current voltage graph for a given metallic wire at two different temperatures T$$_1$$ and T$$_2$$ are shown in given figure, which of the relation is correct from the following?

A
T2>T1
B
T1>T2
C
T1=T2
D
none of these

Solution

## The correct option is B $$T_1 > T_2$$The slope ofthe graph at temperature T$$_1$$ is greater than that at temperature T$$_2$$.So, $$tan \theta_1 > tan \theta_2$$$$R_1 > R_2$$i.e. $$T_1 > T_2$$Physics
