what is resistivity?...what are the factors on which it depends
Asked by | 22nd Mar, 2008, 03:48: PM
Is the ratio of the intensity of the electric field E at any point within the conductor and the current-density J at that is called specific resistance or resistivity of the conductor.
1.) Resitivity depends on the nature of the material.
2.) The restivity of conductor is inversely proportion to the number density of the electron(n). i,e no of free electron per unit volume.
3.) resistivity is inversely proportional to average relaxation time.
4.) resistivity also depends on the temprature
