I dont understand why the plate linked to the negative battery becomes negatively charged. To begin with, each plate is neutral so each contain equal amounts of positive and negative charge. When connected to the battery, the plate linked to the postitive battery terminal becomes positively charged because electrons in a conductor can move, and are attracted from the plate to the positive battery terminal, leaving the plate with only protons. But what causes the electrons on the negative battery terminal to move up to the other plate? Am I right in also thinking that the capacitor will have the same Potential difference across it after its charged? so it will have a more electrons than protons?
