Theory and Operation of Capacitors
In other words, capacitors tend to resist changes in voltage drop. When voltage across a capacitor is increased or decreased, the capacitor "resists" the change by drawing current from or supplying current to the source of the voltage change, in opposition to the change. To store more energy in a capacitor, the voltage across it must be increased.
