In parallel, add the microfarads.
30 microfarads
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.
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.
c =c1 +c2
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).
30 microfarads
When capacitors are connected in parallel, the equivalent capacitance is the sum of the individual capacitances. When capacitors are connected in series, the equivalent capacitance is the reciprocal of the sum of the reciprocals of the individual capacitances.
The effective capacitance of a circuit with multiple capacitors connected in parallel is the sum of the individual capacitances of all the capacitors.
When two or more capacitors are connected in parallel across a potential difference, the total capacitance increases. This is because the equivalent capacitance of capacitors in parallel is the sum of their individual capacitances.
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.
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.
When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitances. In this case, with three 30 micro-farad capacitors connected in parallel, the total capacitance would be 3 times 30 micro-farads, which equals 90 micro-farads. This is because parallel connections provide multiple pathways for charge to flow, effectively increasing the total capacitance.
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.

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.
