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.
