The RC Delay Element
A capacitor is kinda like a tiny little battery. You can charge it with a voltage. And you can use this voltage for a short time until the capacitor is discharged.

Discharging. Discharging a capacitor through a resistor proceeds in a similar fashion, as illustrates. Initially, the current is I 0 =V 0 /R, driven by the initial voltage V 0 on the capacitor. As the voltage decreases, the current and hence the rate of discharge decreases, implying another exponential formula for V.
why do rectified voltage boosts after adding a capacitor?
The average voltage seen at the output in a rectifier-capacitor-resistor circuit depends largely on the rate of discharge of the capacitor. If a tiny capacitor is used then it won''t store any singificant charge and the voltage will look much like it did when the capacitor was discharged.

Ceramic Capacitor Voltage Rating
That means, for example, if the actual capacitor voltage is 50V, select a capacitor rated for at least 100 V. It is a common practice in electronic component selection to derate the ceramic capacitor voltage rating by 50% to prevent explosion as well as VCC. In any electronic circuit designed with ceramic capacitors, this trend should be followed.

How does a capacitor smooth energy?
What this says is: the rate of change of voltage over time (volts per second) is equal to the current (amperes or coulombs per second) divided by the capacitance (farads). If you have a 1 farad capacitor, and you are moving 1 ampere (1 coulomb per second) through it, then voltage across the capacitor will change at the rate …

Capacitors in DC Circuits
When the capacitor is fully charged, the voltage across the capacitor becomes constant and is equal to the applied voltage. Therefore, (dV/dt = 0) and thus, the charging current. The voltage across an uncharged capacitor is zero, thus it is equivalent to a short circuit as far as DC voltage is concerned.
What does the Voltage Rating on a Capacitor Mean?
The only difference is a capacitor discharges its voltage much quicker than a battery, but it''s the same concept in how they both supply voltage to a circuit. A circuit designer wouldn''t just use any voltage for a circuit but a specific voltage which is needed for the circuit. For one circuit, 12 volts may be needed.

If the power supply has a current-limit or overcurrect-trip circuit the ...
Does a capacitor store voltage?
The difference occurs when you want to transfer this stored charge to a circuit. If the circuit requires 2 volts to operate than the 1 Farad capacitor would not be suitable. If your circuit required 5 volts to operate, you would have to use a 0.2 Farad capacitor since it takes 5 volts to charge such a capacitor with 1 coulomb of charge.

Increase capacitor voltage rating by using multiple capacitors?
$begingroup$ @Majenko: The point is to reduce the high frequencies enough so that the active circuit in a voltage regulator can handle the remaining ones. Usually up to a few 10s of kHz is OK. For example, I often use some 950nH 600mOhm 200mA 0805 ferrites. With 22uF capacitance following these, you get one pole at 12 kHz from the R-C action, and …

However, because each capacitor can hold a different capacity, the voltage of each capacitor will be different. We find the voltage of each capacitor using the formula voltage = charge (in coulombs) divided by capacity (in farads). So for this circuit we see capacitor 1 is 7.8V, capacitor 2 is 0.35V and capacitor 3 is 0.78V.
