If necessary, I can calculate the response of two capacitors and their physical resistors in parallel, or one double value capacitor and resistor in series. I think probably the additional resistance in the circuit will swamp out any of the capacitor physical resistance no matter how you configure them..
In the non-ideal case, of course, this does not apply. Two capacitors in series can be considered as 3 plates. The two outer plates will have equal charge, but the inner plate will have charge equal to the sum of the two outer plates.
Or is the discharging process independent of the presence of other capacitors, and it will discharge at its own pace. The rate of discharge of each capacitor has to be the same since for a series connection the current in each capacitor is the same. The C in the RC constant for the circuit is the equivalent series capacitance.
So with the capacitor in series, when one electron leaves a plate, it's most likely a different electron that comes in on the other plate. The capacitor is PARALLEL to the battery. When disconnecting the battery, the led with the resistor will discharge the capacitor. You will see the led go dim to off. I do not see a capacitor in series.
But, no two capacitors are identical due to manufacturing variability, so any chain of capacitors in series is going to have some non-uniformity in the voltage across each cap. Whether or not this is a problem for a given application is a different story, but it's something to be aware of.
If both ends of two capacitors are connected to each other but in such a way that the positive end of one capacitor is connected to the negative end of another capacitor, do we say that the capacitors are connected in series rather than in parallel?
NOTE this is only true if all the capacitors are discharged before you build the circuit. If one of them was charged to voltage V1, i.e. 1V, then no current would flow when you completed the circuit, so the others would remain discharged. Charge is the integral of current and current is the same on all of them.

As capacitors are connected in series, charge on each capacitor must be same. Charge on `6 muF` capacitor = charge on `12 muC` capacitor `6xx10^(-6)xx2 = 12xx10^(-6)xx V_(2)`
Think two equal capacitors in series, one has 1V, the other has 2V, total 3V in series. Then a 3V battery is connected to the ends. There''s no current possible, but your logic states that both caps will finally have 1,5 volts. $endgroup$ – user136077.

This trick are very often seen in audio equipments.
Besides electrolytics, there are other common uses for series capacitors. X2 rated line capacitors are actually two capacitors in series, there is an intermediate metalized film in between.

Detailed answer: If you connect two uncharged capacitors in series to a battery, there will be a current in the circuit until equilibrium is reached. As current flows, the capacitors will start charging, and there will be a voltage drop along each capacitor. In equilibrium, the net voltage drop in the two capacitors will be equal to the voltage in the battery. Reason: Suppose …
The energy stored in the two capacitors is less than the energy that was originally stored in (text{C}_1). What has happened to the lost energy? A perfectly reasonable and not incorrect answer is that it has been dissipated as heat in the connecting wires as current flowed from one capacitor to the other. However, it has been found in low temperature physics that if you …

A more in-depth view is this: Since they are in series, the same current and therefore charge is applied to each capacitor. Voltage is given by V = Q/C.
