ParanoiA Posted March 9, 2011 Author Share Posted March 9, 2011 (edited) I'm not sure I get what you're aiming at here. Could you elaborate? I will certainly try. I'm trying to conceptualize positive charge in terms of electron movement, say, in a battery cell. I can understand the "concept" of moving a positive charge against the field toward the positive source of the field, thereby increasing its potential energy. But I would only see a positive charge move against the field in a solution I guess, because you can't move ions in metals and that's the only way I know of a positive charge "moving" against a field. Otherwise, how does positive charge move? (In electrostatics positive charge redistributing itself was *actually* electrons redistributing themselves, so electrons are moving despite our concept of positive charge moving). Ok, so that's inside the cell. Now, I have the same questions for outside of the cell, powering a circuit. If I have lots of positive charge, again, how am I moving positive charge over wire? We can't do that, and we know that electrons are moving, not positively charged ions nor protons. So I'm stuck again trying to figure out how electrons are moving using a concept that describes the movement of positive charge. I guess that's what I'm struggling with now. Trying to work out electron movement in the context of positive charge movement. It's making it very difficult to grasp. But I can't just forget that electrons are moving around in metals, not positive charges, so I'm also a little frustrated. I'm guessing there's a good reason for all of this though.... Here's another quickie that's been bugging me: We can induce charge in two insulators by using friction - like a balloon and animal fur. If I remember correctly, rubber has more of an affinity for electrons than animal fur and thus takes on a negative charge while the fur, I would suppose is left with a positive charge. So...how do they lose their charge then? After I'm done sticking the balloon to the wall to wow the kiddos, how exactly does the balloon lose its charge and eventually fall to the ground? If only conductors allow electrons to move about their surface, and it took an act of friction to charge these insulators, then how do they casually become neutral again?
