A) Relaxation time decreases
B) Mass of the electrons increases
C) Electron density decreases
D) None of the above
Correct Answer: A
Solution :
Resistance of conductor depends upon relation as \[R\propto \frac{1}{\tau }\]. With rise in temperature rms speed of free electron inside the conductor increase, so relaxation time decrease and hence resistance increasesYou need to login to perform this action.
