How Can Electrolytic Capacitors work for AC Motor Starting?
Sometimes designers create a non-polarized electrolytic capacitor by physically connecting two DC capacitors back-to-back in a circuit, with diodes in parallel, as shown in figure. The diodes bypass the capacitor in reverse polarity, and one diode is in circuit at a time. This way full value of one capacitor is available all the time.
What happens if you put a capacitor in the wrong direction for a
Yes, the capacitor has gotten damaged, at least somewhat. How badly damaged, and how irreversible the damage depends on what voltage was applied for how long. A 50 V capacitor can probably take 5 V in reverse for a few seconds, and probably mostly recover when promptly forward biased. The prognosis gets worse at higher voltage and longer time.

What happens if a voltage is reversed in an electrolytic capacitor?
In case of reverse voltage (negative source to positive terminal and vice versa) will blast the aluminum electrolytic capacitor due to the hydrogen ion theory. In this wrong wiring connection, there is positive voltage across the electrolytic cathode and the negative voltage appears across the oxide layer.
How does a capacitor resist a change in voltage?
Capacitors resist a change in voltage across their terminals; the higher the frequency, the more they behave like a short circuit. In an AC-coupling application, the voltage across the cap is constant (DC bias or 0 V); both sides move up and down with the signal together. i did it with four 30uf caps, all negs connected.
How do polarized capacitors work?
Polarized capacitors can be connected in reverse polarity by adding a DC bias of at least half the AC peak-peak voltage. This way, the entire signal is still positive, but AC-wise the capacitor acts on it normally. In reverse polarity, polarized capacitors are mostly used for bulk storage on power supplies to reduce ripple and to provide short term high current.
What happens if a polarized capacitor is connected with reverse polarity?
Damage: If a polarized capacitor is connected with reverse polarity, the dielectric layer can break down, leading to a short circuit or even an explosion. Performance degradation: Even if the capacitor doesn’t fail immediately, reverse polarity can cause the capacitor to lose capacitance, increase leakage current, and reduce its overall lifespan.
Can an electrolytic capacitor be reverse biased?
Normally a capacitor cannot be reverse-biased for long, or large currents will flow and "destroy the center layer of dielectric material via electrochemical reduction": An electrolytic can withstand a reverse bias for a short period, but will conduct significant current and not act as a very good capacitor. — Wikipedia: Electrolytic capacitor
Can you put a negative voltage on a polarized capacitor?
It is possible to put a negative voltage on a polarized capacitor by adding a DC bias of at least half the AC peak-peak voltage. Some capacitors are unpolarized, and it's perfectly fine to put positive and negative voltages on them. However, this passage specifically mentions applying a negative voltage through an AC signal on a polarized capacitor.
