$begingroup$ @BobSmith, the key difference is that there are resistors in this circuit and so there are three circuit elements connected together on the right hand side when the switch is in position B. In the circuit at the link, when S1 is open and S2 is closed, there are just two circuit elements, the two capacitors, on the right hand side.
When we charge a capacitor, it gains charge q on one of the plates and loses charge q from the other plate, i.e., its total charge remains zero.

The charges on the 4mF capacitor will be equally divided between the 2mF and 4mF, that is Q/2 on each of them. Because if we take one plate of each capacitor and connect them, then the charge will be equally divided. That is if we take the +Q charged plate and connect it to one uncharged plate of the 2mF, then each one will have +Q/2 charge.

For parallel capacitors, the analogous result is derived from Q = VC, the fact that the voltage drop across all capacitors connected in parallel (or any components in a parallel circuit) is the same, and the fact that the charge on the single equivalent capacitor will be the total charge of all of the individual capacitors in the parallel combination.

This proves that capacitance is lower when capacitors are connected in series. Now place the capacitors in parallel. Take the multimeter probes and place one end on the positive side and one end on the negative. You should now read 2µF, or double the value, because capacitors in parallel add together.
The capacitor and resistor are connected in parallel so I think that the resistor will draw a current I=VR but the capacitor is an ideal one therefore has no resistance and therefore draws an infinite amount of current which eventually stops when the capacitor is completely charged so overall. There is a subtle problem here with the logic.
Total capacitance in parallel is simply the sum of the individual capacitances. (Again the "…" indicates the expression is valid for any number of capacitors connected in parallel.) So, for example, if the capacitors in the example above were …
Circuit diagram for parallel capacitor . A capacitor is a device it will be used to store energy.

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.
What happens if in a circuit you connect two equal capacitors in parallel? For capacitors in parallel, the reciprocal of their capacitance equals the sum of the reciprocals of their individual capacitances. The total capacitance will be the product of the two capacitances. For capacitors in parallel, the capacitances add. If you connect two ...
Usually you either combine capacitors in parallel because you want to increase the total capacitance while fitting the components in a certain shape/position, or you just combine capacitors by buying a single capacitor of a larger value. ...

Let''s see some series and parallel connected capacitors in action. This will be a little trickier than the resistor examples, because it''s harder to measure capacitance directly with a multimeter. Let''s first talk about what happens when a capacitor charges up from zero volts.
An RLC circuit consists of three key components: resistor, inductor, and capacitor, all connected to a voltage supply. These components are passive components, meaning they absorb energy, and linear, indicating a direct relationship between voltage and current. RLC circuits can be connected in several ways, with series and parallel connections…

When inductors are connected in parallel, the total inductance is less than any one of the parallel inductors'' inductances. Again, remember that the definitive measure of inductance is the amount of voltage dropped across an inductor for a given rate of current change through it. ... 13 Capacitors; 14 Magnetism and Electromagnetism ;
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.

RC Circuits. An (RC) circuit is one containing a resisto r (R) and capacitor (C). The capacitor is an electrical component that stores electric charge. Figure shows a simple (RC) circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from the initially uncharged capacitor.
Capacitors in Parallel. Figure 19.20(a) shows a parallel connection of three capacitors with a voltage applied.Here the total capacitance is easier to find than in the series case. To find the equivalent total capacitance C p C p, we first note that the voltage across each capacitor is V V, the same as that of the source, since they are connected directly to it through a conductor.
$begingroup$ @Ruslan - I don''t understand what you are saying. The green line in my plot shows that the voltage is NOT a fixed value - it changes over time. During the peak of the cycle, the input voltage of the bridge is high enough to charge the capacitor; but for most of the cycle, the diodes are reverse biased and the capacitor provides the charge / current / voltage for the …

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.
