They were divided into four groups, and five second shocks of 50,000 volts were administered to two of them. The researchers found "statistically significant reductions" in verbal learning and memory; some participants also had trouble concentrating, and they felt overwhelmed and anxious.
Stun guns, which have been used by law enforcement for decades, can temporarily immobilize a person — think of someone who is combative or resisting arrest, for instance — by jolting them with 50,000 volts of electricity. A discharge, also known as a “cycle,” can last five seconds.
A 50,000-volt electric shock is a highly dangerous weapon.
Mostly yes, but often no. If the source of the 50,000V is able to provide a significant amount of current, and that current flows through your heart, you're dead. If it misses your heart and goes through other parts of your body, then death may take a little longer.
Taser initially generates around 50,000 volts of electricity, mainly to allow the wires to pass through the air and through clothing. Once it makes contact with somebody, it drops to 1,500 volts delivered in extremely short pulses.
Assuming a steady current flow (as opposed to a shock from a capacitor or from static electricity), shocks above 2,700 volts are often fatal, with those above 11,000 volts being usually fatal, though exceptional cases have been noted.
The TASER energy weapons use a peak voltage of 50,000 volts so that the electrons can be propelled across a 2 inch air gap.
Dr. Michael S. Morse, a professor of electrical engineering at the University of San Diego, explains that while 10,000 volts can be life threatening in certain circumstances, it's possible for something to have 10,000 volts behind it and be relatively harmless.
At 600 volts, the current through the body may be as great as 4 amps, causing damage to internal organs, such as the heart. High voltages also produce burns. In addition, internal blood vessels may clot. Nerves in the area of the contact point may be damaged.
A combination of voltage AND current kills you. That 400kV is very low current, and the current is so low enough that is unlikely to hurt you because the human skin is usually dry and has high resistance. If you were to break the skin and insert the wires in your blood or something like that, you could kill yourself.
The Tasers used by NSW Police have a current of about 2 milliamps, which is enough to administer severe pain and muscle contractions but not enough to kill. In comparison, Australian wall sockets carry 240 volts and 10 amps (or 10,000 milliamps). Death becomes possible between 50 to 150 milliamps.
An electrical current at 1,000 volts is no more deadly than a current at 100 volts. But tiny changes in a current's amperage can mean the difference between life and death when a person receives an electrical shock.
It can also cause burns, respiratory failure, cardiac arrest, and other serious injuries or death. 7000 volts of electricity can be extremely dangerous and potentially deadly to humans.
People who have been shocked say it hurts a lot
Strikes from stun guns "cause severe, uncontrollable contractions of your muscles, which are very painful," Dr. Jonathan J.
“You're truly stunned and are not able to move anything.” One person who was tased described shooting, excruciating pain that shook his brain like a “peanut in a jar.” Another person said she felt like bees were crawling through her skin.
Loss of consciousness, abnormal brain function, and even seizures can result from being hit by a taser. In addition, a victim may suffer permanent damage from falling.
Thus, in the absence of high voltage, flowing current cannot flow through the body or cause injury or death. For example, a shock of 20,000 volts is passed through the body but the current is extremely low and duration is short, the shock would be harmless.
Voltages greater than 450V a.c. are especially dangerous. At this point the resistance of the skin can break down which significantly reduces the body's overall resistance thereby causing a substantial increase in current.
A good rule of thumb is that when a shock is at or above 2,700 volts, the person often dies or experiences severe injury. At over 11,000 volts, the victim will usually pass away.
You could be killed if you touched the 7KV source with one hand and ground with the other. After that, one might wonder if a 7000-volt electric fence will kill you. It will hurt for about 10 minutes, but it won't debilitate them, leave a burn mark, or kill them.
A static electricity shock can be 20,000 volts or more, but at extremely low current and for an extremely short duration: Harmless. A 9V battery is at an insufficient voltage to drive a dangerous level of current through the body: Harmless.
12V isn't a shock hazard, but it IS a burn hazard.
Even without a short circuit, if you make or break an electrical connection that has a lot of current going through it, the point at which the connection is made can get very hot very quickly and can burn your fingers.
They can be strapped together to form tandems for even higher voltages. A tandem at Oak Ridge National Laboratory produced the highest ever at 25.5MV (a megavolt is 1 million volts).
1 million volts can kill even with a fairly low amperage but if the amperage is low enough 1 million volts will not even hurt.
100KV DC is very dangerous, but like any source if the source resistance is high enough there will not be enough current to kill. This could be an electrostatic discharge, ESD, situation. I have generated 12 inch sparks in the dry desert with a sweater and car seat.
