1. I-V graph for a metallic wire at twodifferent temperatures 11 andshown in the figure below. Which of thetwo temperature is lower and why?T2 is asDelhi 2015T. |
|
Answer» The slope of the given graph gives us the inverse of resistance .resistance of a material increases with increasing temperature because the collision between the molecules increases. In the given graph , given T2 has smaller slope and hence corresponds to higher resistance .Therefore,T2>T1 |
