Capacitors are used to store charges and capacitors alone cannot increase the voltage. Capacitors are connected along with diodes to form the voltage multiplier circuit. Capacitors can be used in many circuits where the output voltage has to be more than the input voltage.
It's the plain English meaning of the word. A capacitor opposes changes in voltage. If you increase the voltage across a capacitor, it responds by drawing current as it charges. In doing so, it will tend to drag down the supply voltage, back towards what it was previously. That's assuming that your voltage source has a non-zero internal resistance.
Capacitance is charge per volt. More capacitance means you need to supply more charge to change the voltage. Supplying more takes longer. The bigger the capacitor, the more charge it takes to charge it up to a given voltage. The resistors limit the current that can flow in the circuit, so a bigger capacitor will take longer.
Power companies use capacitors to regulate the voltage on their primary distribution circuits the bank is shut down and improves the power factor of the circuit, which decreases the amps, which increases the voltage .
Capacitance increases as the voltage applied is increased because they have a direct relation with each other according to the formula C = Q/V C = Q / V. Capacitance decreases as the distance between the plates is increased because capacitance is inversely proportional to distance between the plates according to a relationship C ∝ 1 d C ∝ 1 d.
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 voltage rating on a capacitor is the maximum amount of voltage that a capacitor can safely be exposed to and can store. Remember that capacitors are storage devices. The main thing you need to know about capacitors is that …
If you have a small value capacitor (1uF say), it gets discharged by the load more easily and, when that capacitor gets recharged, that time-window begins earlier on in the …

In many circuits where the output voltage must be greater than the input voltage, capacitors can be used. The output DC voltage is increased by adding capacitors to the full-wave and half …
A capacitor''s ability to store energy as a function of voltage (potential difference between the two leads) results in a tendency to try to maintain the voltage at a constant level. In other words, …
