Electric Fields and Capacitance | Capacitors | Electronics Textbook
When a capacitor is faced with a decreasing voltage, it acts as a source: supplying current as it releases stored energy (current going out the positive side and in the negative side, like a battery). The ability of a capacitor to store energy in the form of an electric field (and consequently to oppose changes in voltage) is called capacitance.

In contrast, when capacitors are placed in series, it is as if the plate distance has increased, thus decreasing capacitance. Therefore capacitors in series behave like resistors in parallel.
