Yes, an electrolytic capacitor behaves like a poor diode and passes current, in the reverse direction. It only damages the capacitor if the DC high enough and is sustained for long
What destroys a polarised capacitor is the large reverse current that flows when its reverse voltage is larger than about a volt. In the reverse series connection of two polarised capacitors this reverse current is limited to the leakage current of the forward biased capacitor. $endgroup$ –

The smaller the current loop, the lower the ESL. A standard surface mount MLCC is rectangular in shape with electrical terminations on its shorter sides. A Low Inductance Chip Capacitor (LICC®) sometimes referred to as Reverse Geometry Capacitor (RGC) has its terminations on the longer side of its rectangular shape.
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
Capacitors in Series. When two capacitors are placed in series, the effect is as if the distance between the outside plates were increased and the capacity is therefore decreased. On an alternating current supply, this effectively increases the opposition to a current flow in a similar fashion to that of resistors placed in series:
The electrolytic cap in your circuit is reverse biased. The reverse biasing of the capacitor removes the isolating oxide layer, so it allows current to pass. If you connect the capacitor the right way after mistreating it this way, the electrochemical process that dissolved the oxide layer is reversed and the capacitor recovers.
The capacitor is charged through the electric motor, than is connected in parallel. The charged capacitor discharges in a few moments into the motor.
Yes "polarised" aluminum "wet electrolytic" capacitors can legitimately be connected "back-to-back" (ie in series with opposing polarities) to form a non-polar capacitor.

$begingroup$ While your polarized capacitor is unlikely to have problems with a small (<1V) reverse bias, you can eliminate this reverse bias entirely by putting a diode (1N914 for example) in series with the collector of T1. This will keep the

If two identical electrolytic capacitors are connected in reverse series, then at sufficiently low voltage, they should effectively behave as two simple capacitors, which leads to a reduction in capacitance by half (such as simple series connection) relatively to sufficiently large voltage (in which the reverse capacitor is equivalent to a short circuit).

TDK C Series Reverse Geometry Multilayer Chip Capacitors are commercial-grade devices with low ESL reverse geometry properties. These MLCCs rotate the orientation of the capacitor by 90°, shortening the current path through the unit and effectively lowering the parasitic inductance value.

In the previous parallel circuit we saw that the total capacitance, C T of the circuit was equal to the sum of all the individual capacitors added together. In a series connected circuit however, the total or equivalent capacitance C T is
Sometimes, a crossover capacitor circuit uses polarized electrolytic capacitors connected in reverse series to create a non-polarized capacitor effect. While this method is a practical solution, it does not perform as well as a dedicated non-polarized capacitor. Nevertheless, it demonstrates a cost-effective way to adapt available components
With capacitors, its the reverse: With resistors, series connections result in additive values while parallel connections result in diminished values. With capacitors, its the reverse: For series capacitors same quantity of electrons will flow through each capacitor because the charge on each plate is coming from the adjacent plate.
Aluminum Electrolytic Capacitor Application Guide If two, same-value, aluminum electrolytic capacitors are connected in series with the positive terminals or the negative terminals connected together, the resulting single capacitor is a non-polar capacitor with half the capacitance. The two capacitors rectify the applied voltage and act as if they had been
phase implementation. This topology adds one energy transfer capacitor (the series capacitor) and can easily be compared to a two-phase buck converter, refer to Section 6 . There are two key differences in the converter connection points. First, the series capacitor is inserted between the high side and low side switch of phase A.
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.
The series combination of two or three capacitors resembles a single capacitor with a smaller capacitance. Generally, any number of capacitors connected in series is equivalent to one capacitor whose capacitance (called the equivalent capacitance) is smaller than the smallest of the capacitances in the series combination.
When capacitors are connected in series, the total capacitance is less than any one of the series capacitors' individual capacitances. If two or more capacitors are connected in series, the overall effect is that of a single (equivalent) capacitor having the sum total of the plate spacings of the individual capacitors.
As for any capacitor, the capacitance of the combination is related to both charge and voltage: C = Q V. When this series combination is connected to a battery with voltage V, each of the capacitors acquires an identical charge Q.
This occurs due to the conservation of charge in the circuit. When a charge Q in a series circuit is removed from a plate of the first capacitor (which we denote as − Q), it must be placed on a plate of the second capacitor (which we denote as + Q), and so on.
Good to Know: The Polarized and electrolytic capacitor won't be connected to the AC supply (both forward and reverse connection) as they are specially designed to be operated only and only in DC circuits in the right way. If so, the capacitor will explode immediately.
