The capacitor physical size is directly proportional to the voltage rating in most cases. For instance, in the sample circuit above, the maximum level of the voltage across the capacitor is the peak level of the 120Vrms that is around 170V (1.41 X 120V). So, the capacitor voltage rating should be 226.67V (170/0.75).

POWER FACTOR CORRECTION – Applied Industrial Electricity
Since we know that the (uncorrected) reactive power is 119.998 VAR (inductive), we need to calculate the correct capacitor size to produce the same quantity of (capacitive) reactive power. Since this capacitor will be directly in parallel with the source (of known voltage), we''ll use the power formula which starts from voltage and reactance:
For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same. Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by

How do I increase the voltage limit by connecting same capacitors?
Of course, for conventional electrolytic capacitors, it is simply more cost effective to use a capacitor with a higher voltage rating, or a bunch of high voltage lower value capacitors in parallel. At a simpler level, for low duty cycle / low load applications, a passive balancing approach can be adopted.
If we were to plot the capacitor''s voltage over time, we would see something like the graph of Figure 8.2.14 . Figure 8.2.13 : Capacitor with current source. Figure 8.2.14 : Capacitor voltage versus time. As time progresses, the voltage across the capacitor increases with a positive polarity from top to bottom.
