A capacitor may have a 50-volt rating but it will not charge up to 50 volts unless it is fed 50 volts from a DC power source. The voltage rating is only the maximum voltage that a capacitor should be exposed to, not the voltage that the capacitor will charge up to.
For a given capacitor, if it's connected to a battery (or other voltage source) with a voltage V , it will store an electric charge Q . This ability is more clearly defined by the "capacitance" of the capacitor. What Is Capacitance?
Remember that capacitors are storage devices. The main thing you need to know about capacitors is that they store X charge at X voltage; meaning, they hold a certain size charge (1µF, 100µF, 1000µF, etc.) at a certain voltage (10V, 25V, 50V, etc.). So when choosing a capacitor you just need to know what size charge you want and at which voltage.
The following formulas and equations can be used to calculate the capacitance and related quantities of different shapes of capacitors as follow. The capacitance is the amount of charge stored in a capacitor per volt of potential between its plates. Capacitance can be calculated when charge Q & voltage V of the capacitor are known: C = Q/V
C = Q/V If capacitance C and voltage V is known then the charge Q can be calculated by: Q = C V And you can calculate the voltage of the capacitor if the other two quantities (Q & C) are known: V = Q/C Where Reactance is the opposition of capacitor to Alternating current AC which depends on its frequency and is measured in Ohm like resistance.
So if a capacitor is going to be exposed to 25 volts, to be on the safe side, it's best to use a 50 volt-rated capacitor. Also, note that the voltage rating of a capacitor is also referred to at times as the working voltage or maximum working voltage (of the capacitor).
