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.
Capacitor Bank Testing: Importance and Procedures Explained
The power factor correction of capacitor banks changes due to moisture, temperature, time, and harmonics. To perform their best, the installed capacitor banks must be tested regularly and maintained to the highest quality. Although capacitor banks of the finest qualities function quite well, their operation can weaken with time.
Capacitor Charging

How do capacitors work?
The amount of electrical energy a capacitor can store depends on its capacitance. The capacitance of a capacitor is a bit like the size of a bucket: the bigger the bucket, the more water it can store; the bigger the capacitance, the more electricity a capacitor can store. There are three ways to increase the capacitance of a capacitor.
