 Electric shock - Wikipedia, the free encyclopedia
The 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.
Electric shocks have been used as a method of torture, since the received voltage and amperage can be controlled with precision and used to cause pain whilst avoiding obvious evidence on the victim's body.
Electric shock delivered by an electric chair is sometimes used as a means of capital punishment, although its use has become rare in recent times.

 Electric Eel Shock - Wikipedia, the free encyclopedia
Electric Eel Shock is a Japanese three-piece rock band, formed in Tokyo in the late 1990s.

 Electric shock precautions
Nobody has yet been injured by a shock in our lab, but since electrical and electronic devices are a ubiquitous part of everyday life, a brief summary of electric shock precautions is given below.
Electric current damages the body in three different ways: (1) it harms or interferes with proper functioning of the nervous system and heart; (2) it subjects the body to intense heat; and (3) it causes the muscles to contract.
Victims of high-voltage shock usually respond better to artificial respiration than do victims of low-voltage shock, probably because the higher voltage and current clamps the heart and hence prevents fibrillation.

 Electrogenesis in Torpedo Rays
The electrical properties of torpedo rays were well known to the ancient Greeks, who were awed by their wondrous ability to make skin tingle, induce numbness, and occasionally to knock a man off his feet.
Early Roman physicians were no less impressed, regarding their electric shocks as possible remedies for ailments such as gout, headaches, and yes, mental illness.
To gain some understanding of the mechanisms at work in torpedoes (and electric fishes in general) for the generation of electric fields (electrogenesis), it is instructive to focus on one of the largest electric rays, Torpedo nobiliana, commonly known as the 'Atlantic torpedo'.

Electric power and electronic appliances are so integrated with modern life that there is a high degree of likelihood that everyone will receive one or more electric shocks in a lifetime.
However, when electric shocks cause damage to humans or even result in death (defined as an electrocution), then improper control or isolation of the associated electric power must be investigated.

 Drive.com.au - Electric shock: it's faster than a Porsche 911   (Site not responding. Last check: 2007-11-06)
Called Eliica, short for Electric Lithium-Ion battery Car, it boasts a neck-snapping 0-100kmh time of just four seconds and a 0-160kmh time of seven seconds, which means the Eliica accelerates faster than a Porsche 911 Turbo.
Flattening the accelerator pedal caused a barely audible whir from the eight in-wheel motors and the sprint to 100kmh was smooth, effortless and quiet.
The mind-boggling acceleration is similar to a 370kW racing car, the only difference being that without a transmission there is no gearshift shock and the linear acceleration pushes the driver back in the seat.

 eLCOSH : Protection from Electric Shock and Arc Flash
Over half of the deaths are from working on energized ("live") electric circuits without proper protection - often when it was not necessary to work "live." At least one-third of the electrocutions occur at low voltage, under 600 volts.
And de-energizing would not be practical during testing of live electric circuits or work on circuits that are part of a continuous process that cannot be completely shut down.
Electric lockout/tagout procedures should be coordinated with all other site procedures for controlling exposure to electric energy and other types of energy sources.
