What voltage can be deadly?

Answer 1

Electrical current is a fascinating and powerful tool. It can be both safe and deadly: the emissions from a Tesla coil, while awe inspiring, pass harmlessly around and through humans; yet, ramp up the current enough, and severe effects can occur.

The major factors that affect a person are: the amount of current, measured in amperes or "amps"; the path the current takes through the body (i.e. through the heart); and the length of time the body is exposed as a circuit.

The voltage, environmental moisture, whether the heart is in a beat or not, and the person's health can also affect the severity of the shock. The following list details effects of current. Note that 1000 milliamperes (mA) equates to 1 ampere (A).

1 mA of current causes a bit of a tingling sensation, but can be dangerous under some conditions.

5mA of current results in a slight painless shock. Strong involuntary reactions can cause injuries to the person.

6-16mA results in a painful shock, and the individual is less likely to have control over their muscles.

17-99mA results in extreme pain, respiratory arrest and strong muscular contractions. Death is quite probable at this point.

100mA-2A results in uneven, uncoordinated pumping of the heart. Nerve damage begins here. Death is highly likely.

At more than 2 amperes, the heart stops, internal organs begin to cook, and sever burns occur. Death is quite probable without immediate medical assistance.

Answer 2

Voltage is not what harms or kills you it is amperage (amps). As little as 0.1 amps can kill.

Voltage is harmless but most accidents happen while on 120 v because it is more common for untrained people to work on. Now to confuse you even more 277v with a load (amps) hurts a lot more than 120 v.

Answer 3

Its not the volts its the amps that do. It can only take 10 mA (milliamps) to the heart to kill you.the volts could be as low as 20 it just matters on the amps.
