The relaxation time in conductors

Write a relation between current and drift velocity of electrons in a conductor. Use this relaxation to explain how the resistance of a conductor change with the rise in temperature.

What are the possible paths of free electrons inside the conductor ?

Define atomic mass unit and electron volt. Establish a relation between them.
