A capacitor will always charge up to its rated charge, if fed current for the needed time. However, a capacitor will only charge up to its rated voltage if fed that voltage directly. A rule of thumb is to charge a capacitor to a voltage below its voltage rating.
The voltage rating is the maximum voltage that a capacitor is meant to be exposed to and can store. Some say a good engineering practice is to choose a capacitor that has double the voltage rating than the power supply voltage you will use to charge it.
A capacitor with a 12V rating or higher would be used in this case. In another, 50 volts may be needed. A capacitor with a 50V rating or higher would be used. This is why capacitors come in different voltage ratings, so that they can supply circuits with different voltages, fitting the power (voltage) needs of the circuit.
A rule of thumb is to charge a capacitor to a voltage below its voltage rating. If you feed voltage to a capacitor which is below the capacitor's voltage rating, it will charge up to that voltage, safely, without any problem. If you feed voltage greater than the capacitor's voltage rating, then this is a dangerous thing.
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).
For the capacitor to charge up to the desired voltage, the circuit designer must design the circuit specificially for the capacitor to charge up to that voltage. 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.

In practice, capacitors deviate from the ideal capacitor equation in several aspects. Some of these, such as leakage current and parasitic effects are linear, or can be analyzed as nearly linear, and can be accounted for by adding virtual components to form an equivalent circuit. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effe…
