Capacitors in series are like resistors in parallel.
CSERIES = C1 C2 / ( C1 + C2 )
Plug 22 and 45 into that equation and you get about 15 microfarads.
14.78 microfarads
In parallel, add the microfarads.
In order to connect four 2 microfarad capacitors such that the total capacitance is still 2 microfarads, connect two pairs of capacitors in series, and then connect the pairs in parallel. It does not matter, since all four capacitors are equal in value, if the center point is connected together or not.
Two similar (non-polarized) capacitors connected in parallel will have double the capacitance of one, while two similar capacitors connected in series will have half the capacitance of one, so the ratio is four.
Capacitors in connected in series result in a higher voltage rating, but lower capacitance. Two 470uF 50V capacitors connected in series will give you a total of 235uF, but you can put up to 100V across the series combination. Two 470uF 50V capacitors connected in parallel will give you a total of 940uF, across which you can put 50V (the voltage rating does not change for capacitors in parallel).

The total capacitance from capacitors that are connected in series are added up inversely; 1/Ctotal = 1/C1 + 1/C2 + ... + 1/Cn, where Cn is the capacitance of the nth capacitor.
capacitance C=C1+C2+C3

When capacitors are connected in parallel, the total capacitance in the circuit in which they are connected is the sum of both capacitances. Capacitors in parallel add like resistors in series, while capacitors in series add like resistors in parallel.

be connected in parallel
For capacitors connected in parallel the total capacitance is the sum of all the individual capacitances. The total capacitance of the circuit may by calculated using the formula: where all capacitances are in the same units.
The equivalent capacitance of a 30uF capacitor in parallel with a 20uF capacitor is 50uF.
Capacitors are one of the standard components in electronic circuits. Moreover, complicated combinations of capacitors often occur in practical circuits. It is, therefore, useful to have a set of rules for finding the equivalent capacitance of some general arrangement of capacitors. It turns out that we can always find the equivalent capacitance by repeated application oftwosimple rules. These rules related to capacitors connected in series and in parallel.
