Capacitors in parallel with voltage sources
The problem is that you can not connect an ideal voltage source of a given voltage in parallel with an ideal capacitor that has some initial voltage different from the source voltage. Once these two are connected, our definitions of "ideal voltage source" and "in parallel" demand that the voltage across the capacitor instantaneously changes.

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 …

capacitance
Two capacitors connected positive to negative, negative to positive are connected in a loop. Whether they are considered parallel or series depends on how other circuit elements are connected to them. The polarity doesn''t matter. That the diagram has a switch between them would make them in series with each other and the switch.

Another popular type of capacitor is an electrolytic capacitor. It consists of an oxidized metal in a conducting paste. The main advantage of an electrolytic capacitor is its high capacitance relative to other common types of capacitors. For example, capacitance of one type of aluminum electrolytic capacitor can be as high as 1.0 F.
Polarised capacitor vs. unpolarised capacitor. Which to use when?
Unpolarised capacitor does not have polarity (there is no + and -). Unpolarised capacitor can be connected in any direction, but this is not so with polarised capacitor. Under what circumstances should one use polarised capacitor and similarly unpolarised capacitor? (Question 2)
Capacitor Polarity: What You Need to Know
Capacitor polarity is the designation of the positive and negative terminals of a capacitor. This is important because capacitors can only be connected to a circuit in the correct polarity. If a capacitor is connected in the wrong polarity, it can be damaged or even explode. There are two main types of capacitors: polarized and non-polarized.

One side of the capacitor is connected to the positive side of the circuit and the other side is connected to the negative. On the side of the capacitor you can see a stripe and symbol to indicate which side in the negative, additionally the negative leg will be shorter. If we connect a capacitor to a battery.
Can I connect a capacitor to a power source directly?
$begingroup$ The easiest thing is to discharge the cap with a resistor, set the supply output to zero volts (or turn it off) and then connect the capacitor when both are at 0 V. Then you can turn on the supply and hopefully it will come up OK with the capacitor there. Lab supplies generally seem to do fine.
