How big is a large capacitor?

Large capacitors generally have a capacitance of up to 10,000 farads, enabling fast charging and discharging and high-current power generation. Large capacitors are generally known as farad capacitors, the basic principle and other types of double layer capacitors, are the use of activated carbon porous electrodes and electrolyte composition of the double layer structure to obtain a large capacity.

Farad capacitors, also known as supercapacitors, double-electric layer capacitors, and gold capacitors, store energy by polarizing an electrolyte. It is an electrochemical component, but in its energy storage process does not occur chemical reaction, this energy storage process is reversible, and because of this supercapacitors can be repeatedly charged and discharged hundreds of thousands of times.
