The relaxation time in conductors

A

Increase with the increase of temperature

B

Decrease with the increase of temperature

C

It does not dependent on temperature

D

All of sudden changes at `400 K`

Text Solution

Verified by Experts

The correct Answer is:
B
(b) Because as temperature increases, the resistivity increases and hence the relaxation time decrease for conductor `(tau prop (1)/(rho))`
