temperatures\[{{T}_{1}}\] and \[{{T}_{2}}\] are shown in given figure, which of the relation is correct form the following?
A) \[{{T}_{2}}>{{T}_{1}}\]
B) \[{{T}_{1}}>{{T}_{2}}\]
C) \[{{T}_{1}}={{T}_{2}}\]
D) none of these
Correct Answer: D
Solution :
The slope of given I-V curve \[\frac{1}{V}=\frac{1}{R}\] i.e., slope \[\frac{1}{R}\] The slope of graph at temperature \[{{T}_{1}}\] is greater than that at temperature \[{{T}_{2}}\] so \[{{R}_{1}}<{{R}_{2}}\] Since resistance increases with rise of temperature hence, \[{{T}_{2}}>{{T}_{1}}\]
