A) \[{{T}_{1}}>{{T}_{2}}\]
B) \[{{T}_{1}}<{{T}_{2}}\]
C) \[{{T}_{1}}={{T}_{2}}\]
D) \[{{T}_{1}}=2{{T}_{2}}\]
Correct Answer: B
Solution :
R increases with increasing temp: \[V=IR\] Slope of graph \[=\frac{1}{V}=\frac{1}{R};\]. Slope of \[{{T}_{1}}\]is more i.e., \[\frac{1}{{{R}_{1}}}\] is more, hence \[{{R}_{1}}\] is less. This concludes that \[{{T}_{1}}\] will be less than \[{{T}_{2}}\] as \[{{R}_{1}}\]is less than \[{{R}_{2}}\].
