Electrolytic condensers: Peculiar features of application

The main advantage of electrolytic capacitors is a high capacitance in a small volume. That's also the reason why electrolytic capacitors are so widely used.
However, an aluminum electrolytic capacitor may have a series resistance of about 1 ohm. The series resistance rises when the temperature decreases and the frequency increases. The latter case is caused by the loss of the dielectric ...
