Theory and Operation of Capacitors

Capacitors react against changes in voltage by supplying or drawing current in the direction necessary to oppose the change. When a capacitor is faced with an increasing voltage, it acts as a load: drawing current as it absorbs energy (current going in the negative side and out the positive side, like a resistor).
