Charge Distribution Upon Contact: How Do Objects of Different Charges Interact?

[benhou]

What happens when two objects of different charges come into contact? Do they distribute the charges per mass, volume, surface area or something else?

Generally you will have electrons move from the negatively charged object to the positively charged one, as rubbing your feet on carpet and touching a doorhandle will demonstrate. I'm not sure, but I believe the charges are distributed purely based on the potential difference in the two objects.
