A disposable flash camera uses a capacitor to power the flash unit, employing an electronic circuit to charge a large capacitor. The flash needs several hundred volts to operate, far higher than the camera's battery can provide. The electronic circuit builds voltage in the capacitor, which then powers the flash

When was the disposable camera invented?
The invention of modern instant cameras is generally credited to American scientist Edwin Land, who unveiled the first commercial instant camera, the Land Camera, in 1947, 10 years after founding the Polaroid Corporation.
What the Difference between digital camera flash and film camera flash?
Mostly trigger voltage is different. Older film flashes used higher voltages, which if used with newer digital cameras can fry the sensitive circuitry in it. A good practice to follow would be to buy flashes made by the manufacturer of your camera, for your camera. Always remember to check the compatibility of your flash with your camera model.
How do you turn a camera into a taser?
Making a tazer is surprisingly easy. All you have to do is buy a disposable camera with a flash. It can be just about any type. All you have to do is take the paper or cardboard off the camera then you should be left with a plastic casing. you might see some little hook like things. You have to undo these. Its a little tricky but it's possible. after that you will be holding the actual device. Now you'll have to look for the capacitor. It's probably near the flash or on the side of the camera. Be careful and do not touch this. Now you just have to find the flash button. Press this and you should hear a sound. If you do then if someone touches the capacitor while your holding the button it should shock them. Be careful because sometimes the capacitor can still shock you even if there's no batteries in it. I f the capacitor stops working you can make them touch the green panel and this will have the same effect as the capacitor. Be careful because my cousin did this and it turned a little part of his finger black. It's cheap but effective.
Which gas is used in flash light?
Many regular flashlights use argon in the light bulbs. For camera flashes, many use xenon.
What was a box camera used for?
To take pictures, like any other camera. The Brownie Box camera by Kodak was one of the first mass produced ones and was named because it looked like a box. The earliest ones had to be sent to Kodak to have their film removed and replaced. They had no flash, no focus or aperature settings and worked outdoors.
Why do disposable cameras have large capacitors?
The capacitor in a disposable camera fills up with power from the battery. It is then used to very quickly pulse the stored energy through the xenon flash tube bulb. The capacitor is capable of discharging all of it's energy almost instantly. A battery on the other hand can only discharge it's power slowly by comparison. So for the high power flash, we use a capacitor to give it that large jolt of power to produce the very bright flash. The "slow" battery then takes it's time (a few seconds) to recharge the capacitor for the next picture.
How many times can you use a camera flash circuit to launch a coilgun projectile?
Given that the battery connected to the camera flash circuit has sufficient energy and that the circuit has no malfunctions, you can use the camera flash circuit indefinitely. Although disposable camera flash circuits are not designed to withstand continuous use, many hobbyist have used them to charge capacitor banks of relatively large size. One problem to consider for using camera flash circuits is its fixed voltage output and the relatively high output impedance leading to long charging times. If you are satisfied with the operations of a camera flash circuit, by all means, go for it. Although, personally I would suggest using a boost converter circuit to charge a capacitor bank at a variable voltage and a much much faster rate. You can learn about them and how to build one at the following links. EE ftw! http://uzzors2k.googlepages.com/boost_converter http://en.wikipedia.org/wiki/Boost_converter
How does a camera flash work?
With older cameras, flashbulbs or flash cubes were used. Then, strobes were developed that used a flash tube. This gave almost limitless flashes. These work by using a battery to charge a capacitor. When the voltage on the capacitor is high enough, it is fed to a xenon (or similar) flash tube, which then fires, giving a very short duration, high intensity flash. It then takes a small amount of time for the capacitor to recharge, before it is ready for the next flash. Some cameras use a dual flash, which has an LED flash as well as a xenon flash.
How was the flash camera invented?
The first known camera flash was used in 1839 by L. Ibbetson.
What is a camera flash diffuser used for?
The flash diffuser on a camera is used to broaden the length of the flash and to soften the image up before taking the picture in order to get a good one when it is dark out.
How does camera flash stun animals?
Camera flash stuns animals because they are not used to that bright of a light. They are also surprised when you take a picture at them with flash because they don't really know what a camera is.
What is a camera flash bracket used for?
When wanting a quality image from a camera, professional photographers often use a flash bracket. The bracket has a flash that is not built directly in the camera and it keeps the images from having the red-eye effect.
How are mirrors used in a camera?
by taking flash. [bulb for seeing this answer]

What are camera bags used for?
I'm just going out on a limb here but I'm GUESSING that it is used to hold a camera or camera accessories like an attachable flash or different camera lenses.
What is mean by capacitive discharge?
Capacitive discharge is when a capacitor (condenser) used to store a larger amount of energy than the supply would be capable of providing and then releasing it quickly into the required circuit. A typical example is a camera flash gun where a small amount of high voltage is generated and built up on a capacitor (this why you have to wait sometimes for the flash to recharge). It then can be released by a trigger device as one pulse to the flash tube. Other common applications are car ignition systems and spot welders.
