The result is a greater total voltage and, by definition (C = Q/V), a smaller capacitance for the system. However, that does not affect the total charge that can go through the system, as this smaller capacitance can be charged to a higher voltage, since each capacitor only "takes" half the voltage.

This means that the sum of two relative charges held by the two capacitors before being connected to each other must be the same as the relative charge of the combined capacitor after being connected. When you place two capacitors in parallel, the total charge of the final system is the sum of the two original charges on the two earlier systems.
As the capacitor gets larger, the amount of voltage droop will be smaller (the slope of the green curve will be less if the capacitance is greater as the capacitor can provide more charge / current without the voltage decreasing). Incidentally, sometimes people will put capacitors of different types in parallel. For example, a large ...
So capacitors are connected in parallel if the same potential difference is applied to each capacitor. Let C1, C2, and C3 be 3 capacitors.

It is equivalent to the diagram to the top right. If two or more capacitors are connected in parallel, the overall effect is that of a single (equivalent) capacitor having a total plate area equal to the sum of the plate areas of the individual capacitors. Thus for parallel capacitors the equivalent capacitance is the sum of the capacitances.
$begingroup$ @AndreasH. With superconductors, you can eliminate the resistance, but you still have inductance. What you have then is an LC tank circuit. It won''t oscillate forever: you can also think of it as a small loop antenna, and the "resistance" in the circuit is the radiation resistance of the antenna.

One important point to remember about capacitors that are connected together in a series configuration.
