About Photovoltaic Energy StorageWhen not using this pin it''s recommended to add a capacitor to ground, this helps filter noise on the reference voltages. It''s not absolutely necessary though, and many designs leave it out as a cost cutting measure for large production runs where the small cost of a capacitor can add up.
About Photovoltaic Energy StorageNo headers If you gradually increase the distance between the plates of a capacitor (although always keeping it sufficiently small so that the field is uniform) does the intensity of the field change or does it stay the same? If the former, does it increase or decrease?

About Photovoltaic Energy StorageTo discharge a capacitor there must be a circuit, a loop, that passes through both terminals of the capacitor. Whether there is also a connection to some "ground" makes no difference to the process. What you might be seeing is that in a specific circuit, one terminal of the capacitor is already connected to ground (or any other bus / …
About Photovoltaic Energy Storage(This is not a claim that capacitors dance the Hokey Cokey.) There are two important reasons why every integrated circuit (IC) must have a capacitor connecting every power terminal to ground right at the device: to protect it from noise which may affect its performance, and to prevent it from transmitting noise which may affect the performance …
About Photovoltaic Energy StorageTo answer you question in short: DC does not pass through the capacitor, AC does. Most noise is AC coupled noise, or/and has AC characteristics, i.e. switching +- some DC value. To accommodate these changes, you use a DECOUPLING capacitor. It simply
