Capacitors for Beginners in Electronics
Electrolytic capacitors are mostly in the micro-Farad range, e.g. 10uF, 220uF, 470uF. The polarity of an electrolytic capacitor is marked on the capacitor body – the negative lead of the capacitor is marked. The longer lead of the electrolytic capacitor is the positive lead: Non-polarised Capacitors. Some non-polarised capacitors are shown below:

Capacitor types
Capacitors are divided into two mechanical groups: Fixed-capacitance devices with a constant capacitance and variable capacitors. Variable capacitors are made as trimmers, that are typically adjusted only during circuit calibration, and as a device tunable during operation of the electronic instrument.. The most common group is the fixed capacitors.

Bi Polar vs. Non Polarized Caps
A bipolar capacitor doesn''t care about the polarity, because it''s built in a special way: "full-thickness oxide layers are formed on both the aluminum foil strips prior to assembly. On the alternate halves of the AC cycles, one of the foil strips acts as a blocking diode, preventing reverse current from damaging the electrolyte of the other one."

Can two electrolytic capacitors be made into a bipolar?
Using two electrolytic capacitors of identical value back to back is routinely used to get a non-polarized capacitor. From this document: . If two, same-value, aluminum electrolytic capacitors are connected in series, back-to-back with the positive terminals or the negative terminals connected, the resulting single capacitor is a non-polar capacitor with half the capacitance to …

Electrolytic Capacitors
A variant of the bipolar electrolytic capacitor is often found in solid tantalum devices. It is based on the back-toback connection. Equivalent polar capacitors are matched together by the manufacturer and placed in a common tube where the cans and cathodes are soldered together (Figure 20.). This design, however, is getting more and more unusual.
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 voltage it has.
How to Tell the Polarity of an Electrolytic Capacitor
Some electrolytic capacitors are intended for bipolar operation through unpolarized methods. These capacitors are constructed with two anode plates that are connected in reverse polarity. In successive portions of the ac cycle, one oxide functions as a blocking dielectric. It prevents reverse current from destroying the opposite electrolyte.
Aluminum electrolytic capacitor
Aluminum electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of aluminum oxide by anodization that acts as the dielectric of the capacitor.
