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.
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.
It's not the volts that kills you, it's the amps. Volts are not current. A Van de Graaff generator found in a school science lab can produce 10,000 volts easily, even 100,000 volts, and they are safe to touch. Though your hair will stand on its end, and you could get an uncomfortable static electricity shock.
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.

They had a minimum of 10,000 volts to stop the dinosaurs from attempting escape, however, this was a severe problem as well, because it could fry a dinosaur, killing it and making it no use to the public eye.
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.
Once the skin is punctured, the lowered resistance results in massive current flow. Ohm's law is used to demonstrate the action. At 1,000 volts, Current = Volts/Ohms = 1,000/500 = 2 Amps which can cause cardiac arrest and serious damage to internal organs.
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.
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.
A typical lightning flash is about 300 million Volts and about 30,000 Amps. In comparison, household current is 120 Volts and 15 Amps.
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.
Man survives electric shock of 14,000 volts which melted flesh from bones.
If you touch 1000 volts then a current of about one ampere will pass through you. The time the current passes can be very small so that it is harmless like in case of static electricity.
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.
"If a healthy person receives a shock of 5,000 volts, they may die on the spot. "In the case of this frozen patient, the task seemed impossible." By comparison in the use of execution by electrocution, a jolt of 2,000 volts is typically used, destroying the brain, followed by shocks with a lessor voltage.
Current Kills, Not the Voltage. But Voltage is must to drive the Current. I.e. Amperes are responsible for electrocution, Not the Volts.
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.
People have stopped breathing when shocked with currents from voltages as low as 49 volts. Usually, it takes about 30 mA of current to cause respiratory paralysis. Currents greater than 75 mA cause ventricular fibrillation (very rapid, ineffective heartbeat).
Remember, it has been suggested a current of only 17 milliamps may induce ventricular (heart) fibrillation. With a hand-to-hand resistance of 1000 Ω, it would only take 17 volts to create this dangerous condition.
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. The high voltage causes electrons to “jump the gap,” a process that “ionizes” the air gap in what appears to the user as a bright arc.
At over 11,000 volts, the victim will usually pass away. 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.
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.
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.
1.0 to 4.3 Amps Rhythmic pumping action of the heart ceases. Muscular contraction and nerve damage occur; death is likely. 10 Amps Cardiac arrest, severe burns, death is probable. Can you think of any situations in which you could face those amounts of electrical current?
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.
