I'm not sure if this question has already been answered yet. I was curious what factors effect the resistance of electrons moving through a wire? From the formula R = p*(L/A) i see mathematically why but I'm curious to the theoretical.
Does an increase in cross sectional area decrease the resistance because there is a greater availability of free elections due to an increase in material?
Or is it the increase in area that the electrons can move through?
Do electrons behave differently near the surface of a wire versus its core?
How does a voltage potential move free electrons down the atoms in a wire? Do they move from atom to atom or flow through?
Thank you for any help or links!
