Ordinary people can generally withstand 36 volts and generally do not electrocute people. Whether a person can be electrocuted or not mainly depends on the amount of current that each organ in each person's body can withstand. In addition, each person's resistance is different, resulting in different currents passing through themselves, so safety is not absolute.
The reasons are as follows: The degree of harm to the human body of electric shock mainly depends on the size of the current passing through the human body and the length of time it is powered. The strength of the current.
The greater the danger, the greater the mortal danger; The longer it lasts, the more likely it is to die. The minimum value of current that can be perceived by a person is called the perceived current, which is 1 mA for AC and 5 mA for DC; The maximum current that a person can get rid of after an electric shock is called getting rid of the current, which is 10mA for AC and 50mA for DC; The current that is life-threatening in a relatively short period of time is called a lethal current, such as a current of 100mA passing through the human body for 1s, which can be enough to make a person fatal, so the lethal current is 50mA. In the case of protection against electric shock, the current allowed by the human body can generally be considered as 30mA.
The body's response to electric current: 8 10mA hands have difficulty getting rid of the electrodes, and there is a sharp pain (finger joints).20 25mA hands quickly paralyzed, unable to get rid of electrodes automatically, breathing difficult.
50 80mA is difficult to breathe, and the atria begin to tremble. 90 100mA respiratory paralysis, after three seconds the heart begins to paralyze and stops beating. According to Ohm's law.
i u r) can be known about the magnitude of the current flowing through the human body, the applied voltage and the resistance of the human body.
Relate. In addition to the human body's own resistance, the human body resistance should also be attached to the human body other than clothing, shoes, pants and other resistance, although the human body resistance can generally reach 5000, however, there are many factors that affect the human body resistance, such as damp sweating, with conductivity.
Dust, increasing the contact area and pressure with the charged body, and the damp and oily stains of clothes, shoes, and socks can reduce the resistance of the human body, so the amount of current flowing through the human body cannot be calculated in advance. Therefore, in order to determine the safety conditions, a safe current is often used instead of a safe current.
To estimate: under normal circumstances, that is, in a dry and electric shock risk environment, the safety voltage is specified as 36V, and for wet and electric shock risk environments (such as metal containers, pipeline welding maintenance), the safety voltage is specified as 12V, so that the current through the human body during electric shock can be limited to a small range, which can ensure personal safety to a certain extent.
-
12 volts, 24 volts and 36 volts are all safe voltages, and there is no danger to people if they can use it normally.
-
No, you can corona people by changing the voltage.
-
The safe voltage for the human body is less than or equal to 36V, and it is fine.
-
China's safety voltage regulations: 36V in general, 24V in humid environment, and 12V in metal containers.

If you don't put it, it should be numb, ** it may burn!!

I only know that the voltage is 36V, and I can't tell if it will be fatal. The degree of harm to the human body of electric shock mainly depends on the size of the current passing through the human body and the length of time it is on. In general, "safe extra low voltage" refers to 36V.
The specified safety voltage is less than 36V, the safe voltage that can be continuously contacted is 24V, and the safe current is 10mA.
The stronger and longer the current is current, the greater the mortal danger.

36V voltage will not electrify people。36 volts is the safe voltage stipulated by the state, and it is the current and not the voltage that determines whether to be electrocuted. The resistance of the human body is not a fixed value, ** about 100,000 euros when dry, generally 1,000 ohms, in wet conditions, the human body has wounds, etc., the resistance will be reduced, and it will also vary from person to person.
The safety voltage level of alternating current specified in China's safety voltage standard:
42V (no-load upper limit less than or equal to 50V) can be used in hand-held power tools and other occasions used in places with electric shock risk, 36V (no-load upper limit less than or equal to 43V), can be used in mines, multi-conductive dust and other places used in running lights and other occasions, 24V, 12V, 6V (no-load upper limit is less than or equal to 29V, 15V, 8V) three gears can be selected for some equipment with charged bodies that may be accidentally touched by the human body.
Industry regulations for safety voltage.
is 36V and the safe current is 10mA for the following reasons: >>>More
220V can't kill people, but you will feel like you are being electrified. If you don't want to be electrocuted, at least wear shoes and don't touch the ground barefoot. It doesn't matter if the voltage flows through the body, as long as there is no voltage difference. >>>More
Not necessarily. Static electricity can be as high as tens of thousands of volts, but because of the short time, people do not die. >>>More
Definitely not, the rated voltage of the electrical appliance is generally much lower than the voltage when it is burned out, and the voltage difference of less than 1V should be no problem, otherwise it can only mean that the quality of the appliance is very poor. However, it is not possible to use voltages that exceed the rated voltage for a long time, which will shorten the life of the device.
The Dead Sea is the deepest depression in the world, and although it is not as salty as the world's saltiest lake, it is also relatively salinity. The Dead Sea is relatively salinity because of its high salinityIt's more than 30%, so there is basically nothing to survive on, and birds that love fish and shrimp don't come here. However, the salinity is relatively high, so the buoyancy is relatively strong, and it is difficult for people to sink into the Dead Sea. >>>More
