What is the effect of heating of a conductor on the drift velociy of free electrons?

How much is the drift velocity of electrons?

How much is the drift velocitu of electrons?

Define relaxation time of the electrons drifting in a conductor. How is it related to the drift velocity of free electrons? Use this relation to deduce the expression for electrical resistivity of the material.

What is drift velocity?

A current of 10A is maintained in a conductor of cross-section 10^-4m^2 . If the number density of free electrons be 9 xx 10^28 m^-3 , calcualte the drift velocity of free electrons. Given, charge on electron, e = 1.6 xx 10^-19C
