I need some clarification on batteries and capacitors. Before a battery is connected to a capacitor, the capacitor is uncharged. When a battery is connected, an electron from one conductor moves toward the positive terminal of the battery, leaving this conductor positively charged. What causes the other conductor to become negatively charged? At this point, the positive terminal loses charge because it has an additional electron. The other conductor is still neutral at this point and something has to cause an electron from the negative terminal to move to the neutral conductor.
