The voltage V and current I graphs for a conductor at two different temperatures 
and 
are shown in the figure. The relation between 
and 
is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
The slope of 
graph gives the resistance of a conductor at a given temperature.
From the graph, it follows that resistance of a conductor at temperature 
is greater than at temperature 
. As the resistance of a conductor is more at higher
temperature and less at lower temperature, hence 
.
