Of course, if you connect two identical capacitors in parallel they will halve their ESD. The only reason to connect a ceramic capacitor in parallel to a electrolytic one, is to make use of its behavior in high frequencies. It would have been best for Ricardo to have supplied an actual representation of the circuit.
These two basic combinations, series and parallel, can also be used as part of more complex connections. Figure 8.3.1 8.3. 1 illustrates a series combination of three capacitors, arranged in a row within the circuit. As for any capacitor, the capacitance of the combination is related to both charge and voltage:
This equation, when simplified, is the expression for the equivalent capacitance of the parallel network of three capacitors: Cp = C1 +C2 +C3. (8.3.8) (8.3.8) C p = C 1 + C 2 + C 3. This expression is easily generalized to any number of capacitors connected in parallel in the network.

Adding a capacitor in parallel with the coil will not only reduce this unwanted reactive power, but will also reduce the total amount of current taken from the source supply. In theory capacitors could provide 100% of compensated reactive power required in a circuit, but in practice a power factor correction of between 95% and 98% (0.95 to 0.98) is usually sufficient. …

When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitors'' capacitances.

Lower ESR. The effective ESR of the capacitors follows the parallel resistor rule. For example, if one capacitor''s ESR is 1 Ohm, putting ten in parallel makes the effective ESR of the capacitor bank ten times smaller.
