I was ripping apart a throwaway camera, and i held down the flash button and i touched something else, and I got a HUGE shock! How could this happen with only like one or two little AA battery's? And how big of a shock was it?

There is a voltage multiplier circuit that is used to power the flash. It stores the energy in a capacitor (a big, usually black or blue, cylinder) and dumps this energy into the flash tube when the flash is triggered. The voltage stored in the capacitor is usually around 300 Volts. There is a lot of energy stored in the capacitor, and though it is not enough to electrocute you except under some really bizarre circumstances, it will give you a nasty bite, as you learned.
You can hear the voltage multiplier circuit running when the flash is being charged. It is the whine sound that you can hear, starting at a really low frequency and going up to a frequency possibly higher than you can hear.

How can three volts give you a shock, if you touch the metal of that camera, while pressing the button, it could have come where the flash is, it needs a powerful jolt of current to operate. As for the amount of that voltage, I have no clue.

Can you do me a favor...next time you try this use your tongue instead. your tongue has 1000s of little nerves and therefore the shock will be less ok. when you do this it will make you feel good actually.
another good ole trick i learned...get an old TV and take the case off the back...turn the tv around and put a couch about 10 feet behind you. touch the capacitor on the tv while it is still plugged in and you will fly to the couch just like superman. feels great the first time you do it.

that is a few issues to recommend for your neighbor: a million. Get a circuit tester. they are less costly (round $4). it is going to tell him if the hollow is undesirable. 2. The range might want to have a nasty plug or wiring. Is it 120 or 240? If it really is 240volts, then a pro must be presented in to learn it. 3. The refrigerator might want to be the perpetrator. it would want to have a nasty floor. a pro might want to inform you. 4. verify to work out if the neighbor has a three into 2 converter plugged into the hollow for the range and refrigerator. if so, he has previous wiring that does no longer contain a floor. it extremely is a nasty concept for heavy abode equipment. 5. in case you've been bare-footed, and he has a concrete pad, you may want to be extra in all probability to get taken aback, noticeably in case you've been nevertheless moist. i do not imagine that is the mission because you touched it with your dry hands. 6. If the refrigerator hasn't been wiped clean, it could be moist below. that would want to have also created a route for the electrical energy if the cord or wires were sitting in water. i do not understand what your neighbor's monetary situation is, yet his first instinct must be to look after this situation. this can properly be a wonder to comprehend, notwithstanding it sounds like your neighbor failed the "being concerned pal" attempt.

It was the flash's built up charge...it happens in the same way a stun gun can produce a charge large enough to stun someone from a 9 volt battery....it's the amps.

Yeah, dude I did that one time and it hurt! Seriously! I felt the shock for almost an hour...
