5.12: Force Between the Plates of a Plane Parallel Plate Capacitor
We imagine a capacitor with a charge (+Q) on one plate and (-Q) on the other, and initially the plates are almost, but not quite, touching. There is a force (F) between the plates. Now we gradually pull the plates apart (but the separation remains small enough that it is still small compared with the linear dimensions of the plates and we ...

Can bipolar capacitors be used instead of polar capacitors?
Bipolar capacitors are linear, and the end result is improved accuracy and less output inconsistencies, greater stability, and less fluctuation. Especially nice in line level circuits, but also handy for reducing noise in power circuits. adpopulum Well-Known Member. Jun 23, 2018
Best Electrolytic Caps for Non-Polarized (nonpolar/bi-polar/bipolar ...
Well the hard rule is no cap > film/foil cap > electrolytic cap. Some basic info to this topic below - Never put audio through a polarized cap that has no voltage offset on either side. It increases distortion significantly at levels greater than a few hundred mV due to the non linear behavior of the cap running at reverse voltage.
Capacitors in Parallel
When capacitors are connected together in parallel the total or equivalent capacitance, C T in the circuit is equal to the sum of all the individual capacitors added together. This is because the top plate of capacitor, C 1 is connected to the top plate of C 2 which is connected to the top plate of C 3 and so on. The same is also true of the …

$begingroup$ This is speculation on my part but may be relevant: Rolled axial-lead capacitors (both paper and plastic-film) in days long ago were marked at one end with a band on the body of the capacitor near where the lead exited the capacitor. This band marked which lead was the most outer layer of the roll. This was occasionally important if …
Electrolytic capacitor
OverviewGeneral informationTypes and features of electrolytic capacitorsHistoryElectrical characteristicsOperational characteristicsCauses of explosionAdditional information
An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor. Because of their very thin dielectric oxide layer and enlarged an…

Can a bipolar capacitor in an AC circuit store even a tiny amount …
A capacitor does not magically work differently in AC. It tries to maintain a steady voltage, causing a current flow to do so. This has some interesting effects when the source is AC (such as leading current, and reactive power) but the mechanism is not different.. So yes, if the AC source is disconnected, the capacitor will try to maintain the …
