In the absence of electric field, the mean velocity of the electrons in a conductor at absolute temperature T is

In the absence of electric field, the mean velocity of free electrons in a conductor at absolute temperature T is :

Thermal speed v of free electrons in a conductor at absolute temperaure T is proportional to

Thermal speed v of free electrons in a conductor at absolute temperaure T is proportional to

The average velocity of electrons in a conductor in the absence of electric field is

The average velocity of electrons in a conductor in the absence of electric field is

How does drift velocity of electrons in a metallic conductor vary with the rise of temperature?

A metallic block has no potential difference applid across it, then the mean velocity of free electrons is (T= absolute temperature of the block)
