Regarding electric potential with respect to a negative charge

  1. Aug 10, 2014 #1
    1. The problem statement, all variables and given/known data

    If I have a electric source charge, does that mean that electric potential increases as r increases (because it gets increasingly less negative as you go farther from the source charge) as opposed to a positive charge in which potential energy would increase as r decreases?

    The reason I am asking this question is because I am confused as to why electrons would accelerate as they reach a point of higher potential. For instance, if an electron moves away from a negative source charge that would mean that the change in electric potential is positive. However it's charge is negative so that means the change in PE is -ve, which means that it has lost potential energy as it moves away from the source charge. Is this explanation correct?

    I think you meant to specify a negative electric source charge
