When power is applied to a capacitor, electrons will start to move away from one end of the capacitor and towards the other. This will cause a negative charge will build up on one end and an equally sized positive charge will build up on the other end, until the power provided can no longer overcome the repulsive force of the electrons on the negative end of the capacitor. Once a capacitor is connected in the opposite way it was charged it will discharge its stored electrons.
