We are going to safely charge 2x 400 farad capacitors in series up to 5.4VDC, and feed that voltage through a DC-DC booster circuit. We are also going to employ a digital voltage display that will be able to read both the charge on the capacitor bank, as well as the voltage at the output of the DC-DC booster.
Charging a capacitor is very simple. A capacitor is charged by connecting it to a DC voltage source. This may be a battery or a DC power supply. Once the capacitor is connected to the DC voltage source, it will charge up to the voltage that the DC voltage source is outputting.
As capacitance represents the capacitors ability (capacity) to store an electrical charge on its plates we can define one Farad as the “ capacitance of a capacitor which requires a charge of one coulomb to establish a potential difference of one volt between its plates ” as firstly described by Michael Faraday.
A capacitor is charged by connecting it to a DC voltage source. This may be a battery or a DC power supply. Once the capacitor is connected to the DC voltage source, it will charge up to the voltage that the DC voltage source is outputting. So, if a capacitor is connected to a 9-volt battery, it will charge up to 9 volts.
For instance, let us assume that we've got a capacitor of capacitance about some 100μF 100 μ F and Also, a commonly used Ni-mH Ni-mH battery of some voltage 1.5V 1.5 V with charge capacities about 2000mA-h 2000 mA-h = 1.08 ×104J = 1.08 × 10 4 J I really bet ya that a common capacitor of some micro-farads won't charge upto that energy.
This is usually recommended. Note: Only charge a capacitor to or below its specified voltage rating. Charging a capacitor to a voltage beyond its voltage rating can destroy the capacitor. To find more information about a capacitor's voltage rating, check out .

Capacitance is the measured value of the ability of a capacitor to store an electric charge. This capacitance value also depends on the dielectric constant of the dielectric material used to separate the two parallel plates. Capacitance is …
Where A is the area of the plates in square metres, m 2 with the larger the area, the more charge the capacitor can store. d is the distance or separation between the two plates.. The smaller is this distance, the higher is the ability of the …
A 1-farad capacitor can store one coulomb (coo-lomb) of charge at 1 volt. A coulomb is 6.25e18 (6.25 * 10^18, or 6.25 billion billion) electrons. One amp represents a rate of electron flow of 1 coulomb of electrons per second, so a 1 …

We have seen in this tutorial that the job of a capacitor is to store electrical charge onto its plates. The amount of electrical charge that a capacitor can store on its plates is known as its Capacitance value and depends upon three main factors.
All you need to charge a battery from a capacitor is to have more voltage charged on the capacitor than the voltage of the battery. The size will only affect how much …
