Show that if the random velocity of the electrons were due to the thermal motion of a classical electron gas, the electrical resistivity would increase with the temperature as T^(3/2)

Question

anonymous · Answer

This is a great question.  First of all, do you have a starting point?

anonymous · Answer

I dont have a starting point besides:
$$v=\sqrt{\frac{3kT}{ m _{e} }}$$

anonymous · Answer

yea... now all you need to do is find the equation relating K.E and Temperature!!!! from the equation you just wrote!!!

anonymous · Answer

1/2 m v^2 = 3/2 kb T?

anonymous · Answer

yes.. now what is the relation between electrical resistivity and drift velocity of electrons?

anonymous · Answer

I am not aware of that relation

anonymous · Answer

thats from derivation of Ohm's law? ..

anonymous · Answer

oh wait.. lemme think.. not so easy :D as i thought

i am trying to find something in my notes and I am having troubles
