Why human body produced electric shock?

Question

when i come out from my car after driving i feel electric shock when i touch the door.

Answer 1

That's from sitting in the seat. Your butt rubs against the interior of the seat and creates static electricity. This transfers throughout your body and can create a shock when you touch something else conductive, like a car door. That is the reason that you should always ground yourself before pumping gas, to avoid an explosion.

Answer 2

The human body is a pretty good conductor of electricity. Electricity always flows towards a "ground" or an item "drawing" the electricity(like an appliance). So when somebody gets shocked it's because the human body offers a quick way to a "ground". Since our bodies work or small electronic pulses to make muscles move; and muscles in order to move only contract, someone who would get electrocuted( if the Amps were large enough) would find themselves in an constant contraction of their muscles. That's why People who grab a live wire get in trouble because the natural contraction of the hand is to close, thus worsening the situation. By the way with the heart being a muscle, too much electrical input would cause to the heart to essentially wreck itself. If the Amps (overall strength) of a current is strong enough then the resulting heat caused by the body not able to effectively and efficiently transfer the energy would basically turn into a low grade resistor and the impeded electricity would cause great heat thus cooking you inside out. At least that's what I hear...

Answer 4

Actually the reason is due to static electricity but it is not due to some butt scratching the seat..
Before me explaining further you should understand this basic electromagnetic theory.....
Flemings' left hand rule: A current carrying conductor placed in a magnetic magnetic field experiences a force... The vice-versa is also true.. i.e Whenever magnetic lines of force are cut by a conductor electricity is produced.
Considering our case... There is always Earth's magnetic field around us.So when the car moves at a great speed, it cuts some lines of the magnetic field and that is the reason why some charges are induced(this is called electrostatic induction).. Usually these charges are negligible and sometimes the stored charges may reach ground via your body when you touch them..

Answer 5

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 milliampere (mA). The current may cause tissue damage or heart fibrillation if it is sufficiently high. A fatal electric shock is referred to as electrocution.
