Identify series and parallel parts in the combination of connection of capacitors. Calculate the effective capacitance in series and parallel given individual capacitances. Several capacitors may be connected together in a variety of applications. Multiple connections of capacitors act like a single equivalent capacitor.
Connecting capacitors in parallel results in more energy being stored by the circuit compared to a system where the capacitors are connected in a series. This is because the total capacitance of the system is the sum of the individual capacitance of all the capacitors connected in parallel.

The voltage ( Vc ) connected across all the capacitors that are connected in parallel is THE SAME. Then, Capacitors in Parallel have a “common voltage” supply across them giving: VC1 = VC2 = VC3 = VAB = 12V In the following circuit the capacitors, C1, C2 and C3 are all connected together in a parallel branch between points A and B as shown.
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 connected in parallel, their capacitance would be Cp = 1.000μF + 5.000 μF + 8.000μF = 14.000 μF.

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.
Since the capacitors are connected in parallel, they all have the same voltage V across their plates. However, each capacitor in the parallel network may store a different charge. To find the equivalent capacitance (C_p) of the parallel network, we note that the total charge Q stored by the network is the sum of all the individual charges:
