This is not really a homework question; I simply don't understand a property of capacitors. How come when some emf is attached to a simple circuit with a capacitor in it, the positive charge all gathers on one plate while the negative charge all gathers on the opposite plate? Why is there not an equal distribution of charge? Additionally, why are the positive charges flowing in the wires? When we discussed charged objects, it was only the electrons that were free to move... I need a giant explanation of all of this. i think i lost something along the way. EDIT: Another quesrion: I just read this excerpt from the text explaining dielectrics: "Less extreme fields can polarize an atom, in essence stretching it so that its electrons tend to be on one side and its positive nucleus is on the other. This turns the atom into a dipole, a body with positively and negatively charged regions." If both ends of the capacitor are equally charged, how are we supposed to determine which side the electrons will veer towards and which side the protons will veer towards? Doesn't the dielectric need to be arranged in such a way that the net field is zero?
