An electron moving in a wire collide again and again with atoms and travel an average distance between the collision that is called mean free path. If the mean free path is less in some metals, what can you say about the resistance of the these metals? For a given conductor , what can you do to lengthen the mean free path?

An electron moving in a wire collides repeatedly with atoms and travels an average distance between collisions called the mean free path. If the mean free path is less in some metals, what can you say about the resistance of these metals? For a given conductor, what can be done to lengthen the mean free path?
In the electric flow, it is found that the resistance (measured in the units called ohms) offered by a fixed length of wire of a given material varies inversely as the square of the diameter of the wire. If a wire 0.01 in. In diameter has a resistance of 0.332 ohms, what is the resistance of a wire of the same length and material with diameter 0.0260?

Earth's lower atmosphere contains negative and positive ions that are produced by radioactive elements in the soil and cosmic rays from space. In a certain region, the atmospheric electric field strength is 174 V/m and the field is directed vertically down. This field causes singly charged positive ions, at a density of 868 cm³, to drift downward and singly charged negative ions, at a density of 624 cm3, to drift upward (see the figure). The measured conductivity of the air in that region is 3.45 x 10-14 (0-m)-¹. Calculate (a) the magnitude of the current density and (b) the ion drift speed, assumed to be the same for positive and negative ions. (a) Number i (b) Number Units Units

In the classic model for electrical conduction, electron mobility u in a metal wire is defined as where v, is the drift velocity of the electrons and E is the electric field in the metal. This parameter is a measure of how freely electrons can travel through a metal when an electric field is applied, such as when the ends of a metal wire are connected to a potential difference.
