Electrolytic capacitor: Properties and operation
66 Electrolytic capacitors consist of two electrodes (anode and cathode), a film oxide layer acting as a 67 dielectric and an electrolyte. The electrolyte brings the negative potential of the cathode closer to the 68 dielectric via ionic transport in the electrolyte [7] (see Figure 2). The electrolyte is either a liquid or a
