On increasing the temperature of a conductor, its resistance increases because

A

Relaxation time decreases

B

Mass of the electrons increases

C

Electron density decreases

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Resistance of conductor depends upon relation as `R prop (1)/(tau)`. With rise in temperature ems speed of free electron inside the conductor increase. So relaxation time decrease and hence resistance increase
