When  Current is Passed to Body... explain Why our Body burns?.can U explain the Chemcal Reaction tak place?

Its is the amount of resistance.  Same reason the wire in a lightbulb grows.  There is some level of electrical resistance, even in conductive materials.  The resistance creates heat and eventual combustion.

Outside heat can bring blood to the surface of the body.  For some people that blood goes to their genitals (those people use them to think), but for the rest of us that blood goes elsewhere.

Ok... I read the answers previously posted and they all sound reasonable close to the truth, so I'll leave them be.. they did fail to mention how a person is actually killed by a lightning strike... So I'll answer this for you...\nYour body uses the flow of charged ions to control many processes (i.e. Muscle movement, nerve signalling).  The flow of charge is more commonly known as electricity.  The average membrane potential in a human is -70 kilojoules(kJ), and the channels in your cells membrane can be triggered by an impulse of only about 20 kJ.  So when you get a current through your body with a potenial of thousands of volts... obviously there is going to be a disruption of the charge gradient.  Depending on the path of the current through the body, the effects will vary... the most dangerous path is for the current to travel through your heart.  Since your Heart is a muscle and is is controlled by an "electrical" signal, this extreme voltage can cause an over fibrulation of the cardiac muscles and essentially render then useless... kind of like if you were to take a slinky and stretch it out as fa as you can... its not goign to contract again, and is not something that can be easily fixed.  Hope this helps!

AgNO3 in solution doesn't burn, unless there's enough acid present.  It does not come off until the skin cells it's on come off (takes several days).  It isn't toxic on your skin either, since it's the silver ion, not the neutral atom.  And, of course, you haven't dipped your entire body in it.

You are electrically charged...it's like a mini-lighting storm... the touching of electrons causes a little clash.\nIt's an energy thing.\n\nHowstuffworks.com has a science section. It can explain electricity.

It is very unlikey that you would survive the current associated with that sort of electroporation, as it would be quite substantial to effect you in the same way it effects the cells used to generate hybridomas. For example, people struck by lightning sometimes display some symptoms you might expect from a minor electroporation effect. In short, the current necessary to have the effect would likely hurt you in many ways, like stopping your heart, than the electroporation would.

b. nothing happens.\n\nIt basically becomes neutral or slightly more acidic or slightly more basic... depends on the amount of each substance...\n\nits [a] because h2 and o2 are gases. adding bases and acids together dont always make gases... usually stay in their original state... usually liquid if thats what your starting with... so [a] isnt the answer because it doesnt refer to all.\n\n[c] is not the answer because mixing bases and acids do not always make water (H2O) [I doubt they have ever]\n\n[d] is not the answer because acids simply does not exist as H-, nor does bases exist as OH+.\n\n[e] is not the answer because... well... lets put it this way... people who have acid reflex or heartburn take an antiacid (like pepto bismol or tums) after they eat or after it occurs... have you seen them explode???

Partly, it's the path the electricity takes.\n\nBut remember, it's not the volts that kill ya, it's the amperes.\n\nI once shorted out the entire electrical system of an old car engine with my bare hands (don't ask why; I was an idiot)  This was thousands of volts - but there's so few amps going through the distributor that all I got was a nasty jerk and a really funky hairdo.  \n\nBut just because I survived that stupidity - don't try it.  You could get a big boo-boo.

It would cause your neurons to fire. That's why when you get zapped by electricity your muscles tense up. If you've ever been in physical therapy they have something where they attach electrodes to your skin and send a small pulse through you and it causes mild contraction of the muscles.\n\nThat's basically it.

Your body runs at a certain temp...when it gets too hot, cells get damaged.......just like a car that get over heated and things break down.

Just a minor nitpick on what others have said.  Electricity can also be the motion of holes, which can be thought of as the absense of an electron.  But generally it is the motion of electrons.

What kills you is not the voltage but the amperes. Current (amps) = Voltage / Resistance. This is ohms law. 10mAmps causes muscular spasms. 30mAmps causes respiratory failure. 75 causes ventricular fibrilation that is the ineffective pumping of the heart. Until this point, the heart can gain back its normal rythym if a defilibrator is used. beyond 4amps, the heart stops functioning and beyond 5 amps, tissue in the body starts to burn.

the immediate effects of heat applications is to draw blood away from the interior and bring it to the surface temporarily. A secondary more lasting effect occurs after the heat is discontinued, when the blood returns to the interior body. Heat increases circulation, metabolism,inflammation,decreases pain, muscle spasm,and tissue stiffness.

Heat is generated through inefficient energy reactions in our body.\n\nAs you may remember from physics class, no reaction is 100% efficient - for example: In a light bulb, not all of the electrical energy in converted into light; some is converted into heat.\n\nThe same is true of our cells, and a some of our energy is released as heat (instead of what is intended!) Muscle movement is especially inefficient, with a great deal of the energy used for muscle cell contraction given off as heat. This is why you get hot when you do exercise!!
