For parallel capacitors, the analogous result is derived from Q = VC, the fact that the voltage drop across all capacitors connected in parallel (or any components in a parallel circuit) is the same, and the fact that the charge on the single equivalent capacitor will be the total charge of all of the individual capacitors in the parallel combination.

6 FAQs about [Voltage of two different capacitors]
Do all capacitors'see' the same voltage?
Every capacitor will 'see' the same voltage. They all must be rated for at least the voltage of your power supply. Conversely, you must not apply more voltage than the lowest voltage rating among the parallel capacitors. Capacitors connected in series will have a lower total capacitance than any single one in the circuit.
What if two capacitors are connected in parallel?
(Thanks Neil for pointing this out) When 2 capacitors are connected in parallel, the voltage rating will be the lower of the 2 values. e.g. a 10 V and a 16 V rated capacitor in parallel will have a maximum voltage rating of 10 Volts, as the voltage is the same across both capacitors, and you must not exceed the rating of either capacitors.
What happens if you connect two capacitors together?
Suppose you have two ideal capacitors with two different voltages across them. The voltage across a capacitor cannot change instantaneously because an infinite current would be required. So if you connect the two capacitors together with ideal wires then at that instant the two capacitors will still have their original, different voltages.
Do parallel capacitors have a lower voltage rating?
Conversely, you must not apply more voltage than the lowest voltage rating among the parallel capacitors. Capacitors connected in series will have a lower total capacitance than any single one in the circuit. This series circuit offers a higher total voltage rating. The voltage drop across each capacitor adds up to the total applied voltage.
What happens if series capacitor values are different?
However, when the series capacitor values are different, the larger value capacitor will charge itself to a lower voltage and the smaller value capacitor to a higher voltage, and in our second example above this was shown to be 3.84 and 8.16 volts respectively.
What is a capacitive voltage divider?
This capacitive reactance produces a voltage drop across each capacitor, therefore the series connected capacitors act as a capacitive voltage divider network. The result is that the voltage divider formula applied to resistors can also be used to find the individual voltages for two capacitors in series. Then:
