They are in series, one end of the first capacitor contacts one end of the other. They are also parallel when the switch is on, because they both connect two ends.

Hence the net charge on the device as a whole is zero.

In short: "high" capacitors (like the 1000 µF) are used to smoothen the voltage signal to a straight DC voltage, "low" capacitors (like the 0.1 µF) are used to suppress interference voltages. So the two capacitors have two different "jobs" to do and can not be replaced by one with the same capacitance.

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.

Effect 1: If we connect capacitors in series, we are making it harder to develop a voltage across the capacitors. For instance if we connect two capacitors in series to a 5V source, then each capacitor can only charge to about 2.5V.

In summary, when two capacitors, C1 and C2, with different initial voltages are connected in parallel, the total charge will remain constant and the voltage will equalize between the two capacitors to reach equilibrium. This is because in electronics, a conductor is simply a container for charge, and the charge will distribute itself evenly between the two capacitors.

There are definitely use cases for chaining several capacitors of the same value, for example to support operation at a higher voltage. 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.
Learn MoreTwo identical capacitors are connected in parallel with an open switch between them. One of the capacitors is charged with a voltage of, the other is uncharged. When the switch is closed, some of the charge on the first capacitor flows into the second, reducing the voltage on the first and increasing the voltage on the second.
Two capacitors are connected in series (one after the other) by conducting wires between points and Both capacitors are initially uncharged. When a constant positive potential difference is applied between points and the capacitors become charged; the figure shows that the charge on all conducting plates has the same magnitude.
We'll also look at the two main ways we can connect capacitors: in parallel and in series. By the end, you'll see how these connections affect the overall capacitance and voltage in a circuit. And don't worry, we'll wrap up by solving some problems based on combination of capacitors.
Then, Capacitors in Series all have the same current flowing through them as iT = i1 = i2 = i3 etc. Therefore each capacitor will store the same amount of electrical charge, Q on its plates regardless of its capacitance. This is because the charge stored by a plate of any one capacitor must have come from the plate of its adjacent capacitor.
When adding together Capacitors in Series, the reciprocal ( 1/C ) of the individual capacitors are all added together ( just like resistors in parallel ) instead of the capacitance's themselves. Then the total value for capacitors in series equals the reciprocal of the sum of the reciprocals of the individual capacitances.
Necessity of capacitor combination : In certain instances, we may not be able to get a required value of capacitance and a required voltage rating. In such instances, to get the required capacitances from the available capacitors and to give only the safe voltage across capacitor, the capacitors have to be grouped in different fashions.
