A) \[{{T}_{1}}>{{T}_{2}}\]
B) \[{{T}_{1}}\approx {{T}_{2}}\]
C) \[{{T}_{1}}={{T}_{2}}\]
D) \[{{T}_{1}}<{{T}_{2}}\]
Correct Answer: A
Solution :
Slope of the V-i curve at any point equal to resistance at that point. From the curve slope for T1 > slope for T2 Þ \[{{R}_{{{T}_{1}}}}>{{R}_{{{T}_{2}}}}\]. Also at higher temperature resistance will be higher so T1 > T2
