As we learnt

 

Relaxation time (T) -

 

Relaxation time (\tau) \rightarrow The time interval between two successive collision of electron with the Positive ions .

-

 

 

 

As with increase in temperature drift velocity increases and hence relaxation time decreases.


Option 1)

Relaxation time increases with increase in temperature

Option 2)

Relaxation time decreases with increase in temperature

Option 3)

Decrease in relaxation time causes decrease in resistivity

Option 4)

Conductivity is independent of Relaxation time
