Confusing question about the movement of electrons

  1. Aug 26, 2014 #1
    Hi guys
    Do electrons move from high to low potential or from low to high potential I think the first one ia right because when electrons are attracted to the negative terminal they have maximum potential energy

    Hi Ahmad

    electrons are not attracted to the negative terminal

    specifically, are you referring to a battery or some other type of power supply ?

    the basics of a battery are that the chemical reaction in the battery/cell causes the separation of free electrons from atoms so that we get an accumulation of electrons (negative charges) at one end of the cell ( the negative terminal) and an accumulation of ions (positive charges) at the other end of cell ( the positive terminal)

    This separation of negative and positive charges produces a potential difference between the terminals

    Does that help ?

    cheers
    Dave
