Capacitor

The membrane can stretch but does not allow water (charges through). We can use this analogy to understand important aspects of capacitors: Charging up a capacitor stores potential energy, the same way a stretched membrane has elastic potential energy. As the capacity of a capacitor decreases the voltage drop increases.

Electrolytic capacitor: Properties and operation

Electrolytic capacitors consist of two electrodes (anode and cathode), a film oxide layer acting as a dielectric and an electrolyte. The electrolyte brings the negative potential of the cathode closer to the dielectric via ionic transport in the electrolyte [7] (see Fig. 2).The electrolyte is either a liquid or a polymer containing a high concentration of any type of ion, although
