AI Customer ServiceSo 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.
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.
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.
When used on DC supplies a capacitor has infinite impedance (open-circuit), at very high frequencies a capacitor has zero impedance (short-circuit). All capacitors have a maximum working DC voltage rating, (WVDC) so it is advisable to select a capacitor with a voltage rating at least 50% more than the supply voltage.
As the capacitor charges up, the current gradually decreases until it reaches zero. Once the capacitor is fully charged, it stops accepting current, and the voltage across the capacitor remains constant. If the voltage across the capacitor is changed, the capacitor will either charge or discharge until it reaches the new voltage.
