When somebody gets an 'electric shock', what actually happens to his body?
454742
An electric shock can occur upon contact of a human or animal body with any source of voltage high enough to cause sufficient current flow through the muscles or nerves. The minimum detectable current in humans is thought to be about 1 mA. The current may cause tissue damage or heart fibrillation if it is sufficiently high. When (and only when) an electric shock is fatal, it is called electrocution.\n\nAn electric shock is usually painful and can be lethal. The level of voltage is not a direct guide to the level of injury or danger of death, despite the common misconception that it is. A small shock from static electricity may contain thousands of volts but has very little current behind it due to high internal resistance. Physiological effects and damage are generally determined by current and duration. Even a low voltage causing a current of extended duration can be fatal. Ohm's Law directly correlates voltage and current for a given resistance; thus, for a particular path through the body under a particular set of conditions, a higher voltage will produce a higher current flow.\n\nShock effects:-\nPsychological\nThe perception of electric shock can be different depending on the voltage, duration, current, path taken, frequency, etc. Current entering the hand has a threshold of perception of about 5 to 10 milliamperes (mA) for DC and about 1 to 10 mA for AC at 60 Hz. Shock perception declines with increasing frequency, ultimately disappearing at frequencies above 15-20 kHz.\n\nPhysiological:-\n\nBurns:- Tissue heating due to resistance can cause extensive and deep burns. High-voltage (> 500 to 1000 V) shocks tend to cause internal burns due to the large energy (which is proportional to the square of the voltage) available from the source. Damage due to current is through tissue heating.\n\nVentricular fibrillation:- A low-voltage (110 to 220 V), 60-Hz AC current traveling through the chest for a fraction of a second may induce ventricular fibrillation at currents as low as 60mA. With DC, 300 to 500 mA is required. If the current has a direct pathway to the heart (e.g., via a cardiac catheter or other electrodes), a much lower current of less than 1 mA, (AC or DC) can cause fibrillation. Fibrillations are usually lethal because all the heart muscle cells move independently. Above 200mA, muscle contractions are so strong that the heart muscles cannot move at all.\n\nNeurological effects:- Current can cause interference with nervous control, especially over the heart and lungs. When the current path is through the head, it appears that, with sufficient current, loss of consciousness almost always occurs swiftly. (This is borne out by some limited self-experimentation by early designers of the electric chair. and by research from the field of animal husbandry, where electric stunning has been extensively studied)\n\nPoint of Entry:-\n\nMacroshock Current flowing across intact skin and through the body. Current traveling from arm to arm, or between an arm and a foot, is likely to traverse the heart, and so is much more dangerous than current traveling between a leg and the ground.\n\nMicroshock Direct current path to the heart tissue

Agree...Can you tell me what happens to peoples energy when they die?

By emergency I'm assuming like a danger situation... as in that Fight or Flight respnse.\n\nYour body releases epinephrine, aka adrenaline.  This has a variety of affects on different systems, striated muscle has an exciting effect, whereas smooth muscle tends to be relaxed by it.\n\nIn the pressence of "adrenaline" you find that you move a bit faster or can possess the super strength of a mother flipping a car to save her child trapped underneath.  Your heart rate increases, blood flow increases, blood pressure drops.  Hope this is helpfull for you.

I'd imagine it would have something to do with the stages of shock. Depending on the situation and your state of being (are you in danger of bodily harm or not) you would go into a state of disbelief or denial. Example: What news you had received "just CAN'T be true!"

The threshold current to feel an electrical shock on human skin is in the range of one to twenty thousandths of an ampere or 1 - 20 mA. Contrast this with the current drawn by a 100 watt light bulb, about 1000 mA or 1 A.\n\nThe voltage required to produce a "shock sensation" varies, depending on the dry or moist nature of the skin contacted. Dry skin requires more voltage to reach the threshold level of shock sensation.\n\nMany years ago it was fairly common practice to "taste" electricity from a 1.5 volt dry cell as a "demonstration of electricity." I doubt this is encouraged today, but I have experienced that sensation by holding my thumb against one end of the cell and pressing the other end lightly to my tongue, ostensibly to determine whether the cell is any good. That worked okay for me until one day I tried to test a 9 volt transistor radio battery by touching both electrodes (that's what the little button and cup on the battery is called) to my tongue. Ouch! I received a very painful shock. After that I used a voltmeter to check batteries.\n\nAlso many years ago, there was a popular device installed in roller skating rinks, bars, and other public places to "test your strength" by grasping two vertical metal handles that were connected to an induction coil, a device for producing high voltage electricity. As one of the handles was rotated the voltage increased, the object being to rotate the handle all the way to its mechanical stop without having to let go. Such devices are extremely dangerous because the current passes through both hands and the chest, possibly inducing a fatal fibrillation in the heart muscle.\n\nIt is best to be extremely careful not to get shocked in the first place. Even very small currents, if they pass through the heart, can be fatal. That is why it is common practice for those who work with "live" circuits to always do so with only one hand, keeping the other hand in a pocket to avoid making a complete circuit through the body.

Various things you do cause a build up of static potential about your body.  How effectively you can release this potential affects how much you zap things/people around you.  Every person's individual resistance to electric current is different.  This along with things like whether or not you are constantly grounded, thus discharging any built up static potential on your body, affect your "electrifying" personality. :P  This is why people employed in working with sensitive electronics use things like grounding wrist straps or ground mats, etc before and while working with the electronic components. The mats and straps help get rid of any static potential build up.\n\nYou're just lucky enough, like my oldest sister, to be able to pop someone else at will.  I always stay out of arm's reach of her in the static filled winter time.

Position the person on his or her back. Make sure the legs are elevated, if possible above the heart level. \nCheck the person's airway to be sure it's clear. Watch for vomiting. \nCheck for signs of circulation (breathing, coughing or movement). If absent, begin CPR. Call 911 or your local emergency number. Continue CPR until help arrives or the person responds and begins to breathe. \nHelp restore blood flow. If the person is breathing, restore blood flow to the brain by raising the person's legs above the level of the head. Loosen belts, collars or other constrictive clothing. The person should revive quickly. If the person doesn't regain consciousness within one minute, dial 911 or call for emergency medical assistance. \nIf the person was injured in a fall associated with a faint, treat any bumps, bruises or cuts appropriately. Control bleeding with direct pressure.

It's like a pressure or shock wave. \nImagine the Hiroshima bomb of menstral cramps. Like that.

The energy that was stored in your body dissipates into the atmosphere, your body begins the process of decay, people who cared about you mourn you for a bit, you are either cremated or filled with embalming fluid after your organs and blood are removed, the rest of the world moves on with life and death.  Pretty much the same thing that happens to everyone...

Brian's answer is correct.\nThe 'shock' you feel is the flow of electric current through your muscles.\nBut voltage is a measure of how much potential the electric source has - the higher the voltage, the more current will flow through you when you hold the terminals. The relationship between the voltage and current is known as Ohm's law. V=I*R. Where R is the resistance between the two terminals (your body, perhaps).\nYou can die with just a few milliamps (1 amp = 1000 milliamps) of current passing through your body IF it flows through your heart (and for a certain length of time). It will induce fibrilations as it interferes with your normal heart electric current.\nHaving said all that, you can feel voltage too without causing current to flow - in the form of your hair standing on end. You need a lot of voltage (thousands of volts) to cause that sort of effect.\nAnd that brings up the next question, why doesn't regular static electricity kill you? It has thousands of volts, so why does it not cause amps to flow through your body (and heart) and kill you? Well, in most normal circumstances the quantity of charge (number of electrons) is very very small - so the current flows for only the briefest of moments and doesn't do any harm to a normal person. However, if you have a pacemaker then you can kill the device and so kill the person! Electronic circuits are typically far less robust than the human body in this circumstance.

You will lose lots of blood, go into shock and die...

Hypovolemic shock is the kind of shock you go into if you suffer from a gunshot wound.You bleed on the inside.You lose circulating blood volume.When you lose circulating blood volume your blood pressure drops.When you blood pressure drops  your heart does not pump out enough blood to your vital organs.Without the blood  you get shock and organ shut down.Yes without replacing the blood by transfusions you will die.However even blood can't save someone who has been shot in a major blood vessel because they will bleed to death quickly Hope I simplified this for you so stay away from guns

Basically when you are excersizing your muscles store energy and when your muscles exceed the amount of force that can be put on them you feel an electric shock released from your muscles due to over working your muscles.

Ninjas used to build up immunity to toxins by poisoning themselves with the very substance they used IN SMALL QUANTITIES....The human body will realize that it is being invaded by a foreign substance and will fight it off.  T-Cells will produce an antibody that destroys the toxin and will remain in the bloodstream encase that toxin ever comes back.  Larger doses over time will increase the antibody load until the toxin would be rendered useless against a person who has "self immunized."  (Ever wondered what the flu shot really was?  TAKE A GUESS!!!)\n\nAs for electroshock.....I don't think that the body can tolerate shock.  (Depending on severity.)  The body relies on electricity in a small part to regulate heart beat.  A few shocks could send the heart into arrhythmia and lead to heart attack.

See source below: \nAbout 20% of people struck by lightning are killed by it. Of the 80% survivors, about 70% percent experience residual effects, most commonly affecting the brain (neuropsychiatric, vision and hearing). These effects can develop slowly, only becoming apparent much later\n\n"Lightning injuries are varied and take many different forms. The most dangerous (and possibly fatal) immediate complications are cardiovascular and neurologic. It must be kept in mind that only immediate and effective cardiorespiratory resuscitation (started by rescuers), followed as soon as possible by emergency medical treatment, can save victims who are in cardiopulmonary arrest, or avert the serious consequences of cerebral hypoxia. Some victims remain in a coma despite intensive resuscitation and die of secondary causes including hemorrhages and multiple lesions (encephalic, cardiac, pulmonary, intra-abdominal)."

Well here is what an EMT does. He/she will handle injuries of all types. Kids falling, cuts scrapes, broken bone, sicknesses, & things to this nature. They handle car accidents which can involve multiple types of injuries. They handle heart attacks, and on arrival may find that the person is in fact dead. They handle pregantcies which can include delivery of the baby. They can at times handle drug overdoses. This can and will at times inclcude handling AIDS patients.Some of the above can be very nasty looking. And as far as AIDS patients, they as a rule WILL inform the tech that he/she has AIDS so you will use standard precautions. It does have it rewarss knowing that you saved a life. But there are downsides as well. When someone dies, be it from an accident or from a heart attack. You don't always save someone's life. At times they do die. If what I have just told you does not deter you then I would look into it a bit more. BUT I can not describe to you in detail how nasty it will get at times. But it does. If you think you can handle real nasty type things, blood guts bones sticking out of the flesh go for it. Good Luck.

The internal circuits of most stun-guns are fairly simple, either based on an oscillator, resonant circuit and step-up transformer or diode-capacitor voltage multipliers to achieve the continuous, direct or alternating high-voltage discharge may be powered by one or more 9 V battery depending on manufacturer, and model.  The recipient of the tazer shock (poor fellow) is actually imobilized as two metal probes touch the skin and send a high-voltage current through his or her body, causing great pain and temporary paralysis.
