A) T>T,
B) T,<T,
C) T,=T,
D) Nothing can be decided
Correct Answer: A
Solution :
[a] Slope of the graph gives us reciprocal of resistance. Resistance at temperature \[{{T}_{1}}\] is greater then that at temperature \[{{T}_{2}}\]. Because the resistance of metallic wire is more at higher temperature than at lower temperature, \[{{T}_{1}}>{{T}_{2}}.\]You need to login to perform this action.
