MCQ
The relaxation time in conductors
- AIncreases with the increase of temperature
- ✓Decreases with the increase of temperature
- CIt does not depend on temperature
- DAll of sudden changes at $400\, K$
✓
Answer
Correct option: B.
Decreases with the increase of temperature
b
(b) Because as temperature increases, the resistivity increases and hence the relaxation time decreases for conductors $\left( {\tau \propto \frac{1}{\rho }} \right).$
(b) Because as temperature increases, the resistivity increases and hence the relaxation time decreases for conductors $\left( {\tau \propto \frac{1}{\rho }} \right).$
