How about capacitors be used in series and in parallel?

Shunt capacitor: the shunt up of the capacitor equals the increase in the area of two metal electrodes, so the total capacitance after the parallel is increased, equal to the sum of each capacitance, C =C1+C2 +C...

When capacitors are connected in parallel, the voltage on each capacitor is equal to the total voltage. Therefore, if several capacitors with different working voltages are connected in parallel, the lowest working voltage must be used as the working voltage after parallel operation. When the electrolytic capacitor is connected in parallel, the positive pole should be connected with the positive pole in parallel, and the negative pole will be parallel to the anode.

The series of capacitors:

the result of the capacitor series is equal to the increase of the thickness of the insulating medium (that is, the distance between two metal electrodes), thus the total capacity decreases, and is less than the capacitance of one of the smallest capacitors. The reciprocal of the total capacity is equal to the sum of the capacitance reciprocal of each capacitor, that is, the 1/C total =1/C1+1/C2... 1/Cn. if two capacitors are connected in series, the total capacity after the series is half of the capacitance. The working voltage of series capacitor (C) is equal to the sum of the working voltage of each capacitor under the condition of equal capacitance. When the electrolytic capacitor is connected in series, the positive pole should be connected with the negative pole.

Attention should be paid to the fact that there is too much difference between capacity and voltage in practical application。
