Alas, another one of my conceptual struggles in regards to current. In regards to a circuit in which a solid metal conductor is used to connect the positive and negative terminals of a battery, I do not understand the idea of conventional current. I understand the way negative charges (carried by electrons) move- in the opposite direction of the electric field. I am under the impression that only negative charges move in such a circuit. I do not see why there would be a "convential current" (positive charge flow) in the opposite direction of the electron flow. And if there were such a positive flow in the opposite direction of the electron flow, how would the two flows manage to get through the conductor? Wouldn't they just attract each other and get "mixed up" for lack of a better term? Is there even positive flow in such a wire?
