Humans have died at as low as 42 volts. Time is also a factor. A current of 0.1 ampere for a mere 2 seconds can be fatal. As Voltage = Current x Resistance the current depends on body resistance. The internal resistance between the ears is only 100 ohms, while it is around 500 ohms when measured from finger to toe.

It takes between 0.1 and 0.2 amps to kill a human being. Shocks above 0.2 amps are not considered to be lethal because a human can be revived from that voltage if the victim receives immediate medical attention. A current over 0.2 amps is likely to cause severe burns and stop a person's breathing.

200 mA (0.1 to 0.2 amp) are lethal. Currents above 200 milliamps (0.2 amp), while producing severe burns and unconsciousness, do not usually cause death if the victim is given immediate attention. Resuscitation, consisting of artificial respiration, will usually revive the victim.

Let’s consider an electric shock of 0.1 Amperes of current through the chest area (enough to stop the heart and breathing): Let’s assume an electrical resistance of about 300 ohms between the upper left arm and the upper right arm (the contact poi...

• How Many Currents Can Kill You? The answer is very little. A current of as little as 0.007 amps (7mA) across the heart for three seconds is enough to kill. 0.1 amps (100mA) passing through the body will almost certainly be fatal. Source: Thenounproject

Though there are plenty of warning signs that read, "Danger! High Voltage," it is actually the amperage through the body that kills you. The range of amps needed to kill a person varies. Here's a primer, taken from OSHA, discussing AC wall current shocks in mA (1000mA = 1A): These are just general guidelines.

In short, high voltage with a few micro amperes cause nothing to the human body like in high voltage supplying cathode ray tube in traditional TV set or high static voltage in the comb. on the other hand high current with hundredth of ampere with ten, twenty or thirty or more make nothing to human bodies like electric welding machine as the amount of voltage is not enough to push that level of high current in the human body as there is a path with least amount of resistance as compared to ...

An electrical current at 1,000 volts is no more deadly than a current at 100 volts, but tiny changes in amperage can mean the difference between life and death when a person receives an electrical shock.

Back to your question, the safe limit for DC voltage is any voltage that when applied to your body will generate less than lethal current. As per various sources (you can easily google them), any current over 10 mA will produce a severe shock whereas current over 100 mA is lethal.

In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.
The human skeleton of an adult consists of around 206 to 213 bones, and there are 300 bones in children, depending on the counting of sternum (which may alternatively be included as the manubrium, body of sternum, and the xiphoid process). It is composed of 300 bones at birth, but later decreases to 80 bones in the axial skeleton and 126 bones in the appendicular skeleton.
The amount of water in the human body ranges from 45-75%. The average adult human body is 50-65% water, averaging around 57-60%. The percentage of water in infants is much higher, typically around 75-78% water, dropping to 65% by one year of age.
Up to 60% of the human adult body is water. According to H.H. Mitchell, Journal of Biological Chemistry 158, the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.

How to Calculate Dog Years to Human Years The long-believed "1 dog year = 7 human years" theory is not supported by science. Different breeds age differently, with small dogs in general living longer than large ones. A 2019 study suggests a new formula based on changes made to dogs' DNA over time.
The percentage of water varies according to your age and gender. Here's a look at how much water is inside you. The amount of water in the human body ranges from 45-75%. 1 The average adult human body is 50-65% water, averaging around 57-60%.
