A high-voltage Parallel Resonant Converter with single capacitor as an output filter Abstract: One of the major drawbacks of high-ratio step-up transformers is the high value of their secondary side capacitor. This value is reflected at the primary side giving rise to a non-desirable one. There are some converters [1][2][3] which include this ...
Introduction to the Series Capacitor Buck Converter
because they must blank the initial portion of the high side on-time. Narrow pulse width is often a limiting factor in high voltage conversion ratio applications. Consider a buck converter with a 10:1 voltage conversion ratio operating at 5 MHz. As shown in Figure 4, the high side switch nominal on-time is 20ns.

Capacitor Basics, Working and Different Types of Capacitors with …
The maximum voltage this sort of arrangement can handle is the voltage of the smallest capacitor, since in the voltage is common to all the caps. An example should clear this up. Supposing you have two capacitors, one with the ratings 25V 470uF and the other 35V 1000uF.
Why do we use two parallel capacitors in a voltage regulator …
In short: "high" capacitors (like the 1000 µF) are used to smoothen the voltage signal to a straight DC voltage, "low" capacitors (like the 0.1 µF) are used to suppress interference voltages. So the two capacitors have two different "jobs" to do and can not be replaced by one with the same capacitance.

A capacitor can store electric energy when disconnected from its charging circuit, so it can be used like a temporary battery, or like other types of rechargeable energy storage system. Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed. (This prevents loss of information in volatile memory.)
resistors
I need to discharge a 4.4mF (millifarads) capacitor storing 1200V in about 5 seconds. I did the t=R*C'' and got a resistance value of approximately 227ohms.I did a calculation for the energy in the capacitor E=1/2*C*V^2 and got out 3168J. I had a look online at resistors and they either have the power or voltage but not both.
