Answer: An electron moving in a wire collides repeatedly
Chapter 23, Problem 14E(choose chapter or problem)
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?

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?
ANSWER:Step 1 of 2
The resistivity is inversely proportional to the mean free path
