Are low ESR capacitors bad for power supply decoupling?
A common theme in electronics is to plop down 0.1uF capacitors at several locations on a board in order to decouple the various places where varying power currents are drawn from the power lines. Given that point-to-point inductances in a board (between the various decoupling capacitors) tend to be of order 10-50 nH, we can therefore expect to see various resonances

Why is capacitor placed in parallel for power factor
Current can only flow in a closed loop, so a series capacitor cannot keep reactive current from flowing through the distribution grid, which is the very thing that power factor correction seeks to avoid in order to avoid the
Are capacitors ever used in series in a DC circuit?
Yes. An electrolytic capacitor is polarized because if it wired backwards, it causes a degradation of the dielectric. If you wire two polarized electrolytics in series with opposite polarities (positive to positive or negative to negative), the DC voltage drop occurs across the capacitor with the correct polarity and prevents this degradation.

Best capacitors for power supplies update
There may well be audible differences between different types of capacitors for a given power supply/amplifier setup, but it''s far more likely to be due to differences in impedances and resonances which may be specific to that circuit rather than the magical properties oft claimed for some brands of capacitors. better than parallel Kendeils
To use capacitor or diode in latching relay set-up? Which is better
In the former, during the switching process, power supply B turns on, and both power supply A and power supply B will briefly overlap (thus the need for Schottky diodes for each, otherwise problems cause by competing DC power supplies ensue) before one is cut off by a relay, thus ensuring a smooth transition of power supply.
