What happens if a positive or negative current passes through the human body?

If the current passing through the person is small, then there will be no effect on the person or even a sensation. This is the case, for example, when using a voltage tester to test the AC voltage. The key is the amount of electrical current passing through the body. Beyond a certain level, it will be harmful to the human body.

The main thing is to see the intensity of the current that will cause different degrees of damage. Is it alternating current or direct current.

If it is a strong current, it will cause an electric shock, which may lead to death.

If the current is very weak, then it is fine, for example, if the safety voltage is less than 12 volts DC.

The Tibetan service current you are talking about should be what we describe as alternating current! If the safe voltage exceeds 36 volts passes through the human body, it will cause extremely great harm to the human body, and even fatal.

How do positive and negative currents pass through the human body? How do positive and negative currents pass through the human body? Then it is very dangerous to be electrocuted.

Whether conductive or non-conductive electricity and whether living organisms can live or not are two different concepts.

The heart has a limited ability to withstand electric current, and 30mA can make the heart muscle tremble, and the person will burp.

The positive and negative currents mentioned in the question are instantaneous alternating current, and 100mA of alternating current can be fatal when the alternating current passes through the heart.

Answer: Regardless of whether it is a positive current or a negative current, as long as the current exceeds the human tolerance value, then the person will be electrocuted.

First of all, let me tell you that the resistance of your personality is not small. Another point is not to take a long time, because millions of cells die every second, and the advantage is that it can kill bacteria and viruses or something.

On the other hand, many of people's vital activities require nerve regulation, and the current in the neurons is weak, which can transmit relevant information and give a strong current to the human body, so that the vital activities are disordered and seriously lead to death.

Hope these are helpful to you.

The current passing through the human body is more than 30mA, and the leakage protection switch for civil use is to operate after 30mA.

The voltage can withstand tens of thousands, but the current must not be large!

The safe voltage for the human body is 36V

The DC safety current is 50mA

The AC safety current is 10mA

The insulation resistance value of the human body is 800-1000 ohms, but this is inconsistent with people's fatness, thickness, age, height and shortness, and of course, it is also different from people's physical strength. The safety current standard in the United States is 16mA, and the current standard in China is 14mA. In general, the human body has a feeling of numbness in the power frequency AC 1MA or DC 5MA human body, and can get rid of the power supply below the power frequency AC 14MA, if the human body causes numbness or severe pain under the AC power frequency current 20-25MA DC 80MA, or breathing difficulties, can not get rid of the current, and may cause life danger for a long time.

Will die! Because it's the current, not the voltage, that can kill people!

The maximum value of the safety voltage is constant, and the resistance of the human body is basically stable under normal circumstances, so the maximum current is also basically stable. Therefore, it will not have a great impact on the body at a safe voltage.

The resistance of the human body is basically stable, and it is relatively large, when the voltage is within the safe range, there will be no excessive current through the human body, if there is too much current through the human body, then it will be a life!

In severe cases, ventricular fibrillation can lead to death.

It depends on whether there is an absolute source under the feet, as well as the location of the electricity, if the current passes through the internal organs, the possibility of death is very high, and some pass through the feet and hands, there is no big problem.

Muscle shaking affects nerve potential conduction.

The way the electric current passes through the human body is different, and the damage to the human body is also different. If an electric current is passed through the heart, it can cause ventricular fibrillation, which in turn interrupts blood circulation and leads to death. Electric current passes through the central nervous system, which can cause central nervous system dysregulation and lead to death.

Passing an electric current through a person's head can cause an immediate coma, and if the current is too high, it can cause damage to the person's brain and even death.

The shorter flow path of electric current from the left hand to the heart of the chest is the most dangerous route of electrical current. Hand-to-hand or hand-to-foot is also a dangerous route of electricity. Although the current route from foot to foot is less dangerous, it can cause a fall due to spasms, causing an electric current to pass through the body and cause a secondary electric shock.

It depends on the size of the current, the larger the current, the more dangerous it is.

When the human body touches the conductive parts of different potentials at the same time, the potential difference causes the current to flow through the human body, which is called electrical contact. Depending on the size of the contact current and the length of the duration, it has different effects on the human body. The current is harmless to the human body, and some medical electrical equipment used for diagnosis and treatment can also cure and save people through a small amount of current when it comes into contact with the human body, which is beneficial to the human body, and this electrical contact is called micro-electrical contact.

If the current passing through the body is large and lasts too long, it can cause injury or even death, and this electrical contact is called electric shock. Electric shocks are life-threatening, so electrical professionals should understand the effect of electric current passing through the body in order to take the correct and effective precautions to avoid electric shock accidents.

No more than 24V is harmless.

Fifty-five percent of the damage.

Harmful to the human nervous system is through microcurrents.

to control the whole body.

If you pass an electric current through the human body often, the human body will inevitably be affected.

Heart. Because the strong electrical current affects the autonomic tissue of the heart, it can lead to cardiac arrest!

In fact, they are all dangerous, but it is the heart, lungs, brain and central nervous system that cause the fastest deaths. If the current is small, it can activate these organs to save people, and if the current is large, it will burn out these organs and directly cause death, from the feeling of the electrocuted person being rescued, when the high current passes through the body, the person will not feel any sense and will not feel numb pain like touching 220v.

When an electric current passes through the heart, there is no hope of survival.

Heart and brain, a little longer when an electric current is passed can damage the heart and brain tissue.

The passage of electric current is the most dangerous.
