Capacitor
Capacitor is the electronic element that builds and holds the energy required to power a camera's flash unit. The capacitor will only store the energy for short period of time before it dissipates and needs to be rebuilt.
Capacitors - Devices that store energy by collecting charge on plates (see How Capacitors Work)
Inductors - Coiled lengths of wire that store up energy by generating magnetic fields (see How Inductors Work) ...
Capacitor.
Electrical component once more commonly known as a condenser. Stores electrical energy supplied by a power source and can discharge it more rapidly than the source itself.

Capacitor
Unit for storing and releasing a pulse of electricity. Used in flashguns to hold the charge.

capacitor
an electrical circuit element consisting of two metallic plates separated by a dielectric or insulating material such as glass, ceramic, mica, or other non-conducting material used to store an electrical charge temporarily.
-Capacitor - device that builds and stores electrical charges. Used in electronic flash and some forms of electronic shutters.
In a capacitor or system of conductors and dielectrics, the property that permits the storage of electrically separated charges when potential differences exist between the conductors.
Electronic flash uses a discharge tube filled with xenon gas and is supplied with a powerful charge of electricity from a capacitor. The flash is triggered by means of an electrical current that ionizes the gas.
An image is projected by a lens on the capacitor array (the photoactive region), causing each capacitor to accumulate an electric charge proportional to the light intensity at that location.
The way that a digital camera increases the ISO is to apply a greater amount of amplification to the voltages that come from the pixels' capacitors.
Although precision resistors and capacitors are cheaper to make than gears, these shutters carried very high prices and soon disappeared from the market. My thought is that the makers attempted to recover tooling costs too fast.
It's obvious that the load of the capacitor and therefore the burn duration of the flash bulb is limited. When the capacitor is exhausted before proper exposure is reached, the image is considered underexposed by the camera.
Invest in one of the new ultra-compact flux-capacitor devices first introduced to the general public in the movie Back to the Future.
The figure expressed (300 for example) means that the flash head stores 300 Joules in its capacitors.
Indicates the energy content of the storage capacitors in an electronic flash. One Joule is the light output given by one watt burning for a second.
When in manual mode, the 430 EX Canon flash gives all its power to the scene, at times empting it's capacitor in a single flash.
Electronic flashes work by charging up a capacitor with electricity, then releasing the stored-up power in a split-second burst of light.
After a charge-coupled device takes in and transfers each slice of a given image, the last capacitor of the series converts the series of charges into a given voltage that is then stored in a digital camera's (or a telescope's) memory.
You can shorten start-up time even further by switching off the flash before turning off the camera, eliminating the need for the flash capacitor to charge before use.
Fan cooling: Placing the modeling light, power supply, and flash tube (that's the glass tube that produces the flash from a capacitor filled with energy from the power supply) inside a single housing creates heat.
Some simply have a capacitor to hold enough charge temporarily while you put in a new battery, but many have a small extra battery specifically intended to keep the clock from forgetting what time it is when the main battery is out.
A battery or batteries charge a capacitor to a high voltage. Once sufficiently charged a 'ready light' comes on. As the shutter release is pressed a charge is sent across a gas filled flash tube.
Charge Coupled Device. An integrated circuit (microchip) consisting of a group of charge storage cells (tiny capacitors) with the ability to pass charge from one to the next, in a line, like firefighters passing buckets from one to the next.
Once fired, your strobe needs time to recharge the capacitor to be ready for the next shot. A ready light indicates the recharge, but be aware that usually the ready light comes on when the strobe is only at about 80 percent of its full capacity.
Equipment that gives a brief, brilliant flash of light by discharging an electronic capacitor through a small, gas-filled tube. Given time to recharge, a unit gives many thousands of flashes, usually triggered by contacts within the camera shutter.
Thyristor: A type of circuitry used in automatic flash units which returns unused energy to the capacitor after each shot. This design reduces recycling and power consumption substantially.
The audible signal, is a singular beep that sounds off when the capacitor has been recharged. The audible recycling signal can also be shut off should it become distracting or interruptive. [figure 28] ...
This mode is rarely useful because it reduces flash range (each part of the sensor gets only a flash burst that is weak from the small part of the capacitor's slowly-stored energy used for it), ...
Watt/seconds, W/s, Joule, J (flash) The electrical current stored within the capacitors of electronic flash units, ...
Each pixel is a kind of combination of photo diode for light-sensitivity and capacitor for analogue value storage. Many digital cameras use CCDs as their image sensor, although some use CMOS or other devices instead.
each shot you also can shoot with the flash at several frames per second. For instance, if the flash only needs 10% of it's full power for each shot you can make ten shots as fast as you want before draining all the power from the flash's capacitor.
A compromise auxiliary battery pack available for both Canon (Compact Battery Pack CP-E4) and Nikon (SD-8A Hi-Performance Battery Pack) contain an extra set of AA batteries and a capacitor that furnishes the flash with high-voltage output.
