A capacitor attached to the flash gun charges up for a few seconds using energy from your camera''s batteries. (It takes time to charge a capacitor and that''s why you typically have to wait a little while.) Once the …
If you mean charge it up to the source voltage, then yes, you can get arbitrarily close to "full charge". You could use a DC-DC converter to increase the available source voltage to the rated voltage of the capacitor in order to get a full charge in the first sense.
In my understanding, theoretically, when an uncharged capacitor is connected directly to a battery of, let''s say, 9 volts, instantly the capacitor will be charged and its voltage will also become 9V. This will happen …

The charge time is the time it takes the capacitor to charge up to around 99%, reaching its charger''s voltage (e.g., a battery). Practically the capacitor can never be 100% charged as the flowing current gets smaller and smaller while …
1 · Q = C * V. where: Q = charge stored in the capacitor (coulombs); C = capacitance of the capacitor (farads); V = voltage across the capacitor (volts). This formula highlights the direct relationship between capacitance, voltage, and charge, emphasizing that increasing either the capacitance or the voltage will result in more stored charge.

Similarly if you keep drawing current from a charged capacitor, its voltage will keep falling until it reaches 0V (and continue to fall, even, if current keeps flowing in the same direction). This means that a cell''s voltage is well defined, but the voltage across a capacitor can be arbitrarily high.
If a capacitor is charged with a battery, the capacitor is still electrically neutral. The battery has given up some of its stored energy to the capacitor (and some to heat). There is no electrical charge stored in the …

The capacitors filter this drop by supplying the appropriate voltage to keep the circuit smooth. As the voltage rises back up again, it recharges the capacitor. A leaky capacitor has the effect of a large rated capacitor that leaks and keeps the circuit from working properly. In most cases, you can over rate a capacitor and get away with it.
