The human body itself is a resistor, except for the hair. In winter, electricity is generated between people because of human friction, and in winter, when the weather is dry, there is no moisture in the air as a conductor to export the electricity generated, so it is easy to react with people or other objects.
-
People also produce points through friction! A blink of an eye can generate 0.2 volts of power.
-
Yes. The longer the current lasts, the resistance of the human body.
The decrease due to sweating and other reasons leads to a further increase in the current passing through the body, and the risk of electric shock increases. In addition, the longer the current lasts, the central nervous system of the person.
The stronger the reflection, the greater the danger of the electric shock.

In general, the resistance of the human body can be considered as 800 1000.
The resistance of the human body is in the range of about 2,000 ohms to 20 megaohms. **When sweating, about lk**When there is a wound, about 800. When the human body is electrocuted, the larger the contact area between ** and the charged body, the smaller the resistance of the body shouted.
When the human body comes into contact with a charged body, the human body is connected to the circuit as a circuit element.
Human impedance usually includes external impedance (related to the clothing, shoes and socks worn at the time of the electric shock, as well as the dampness of the body, ranging from a few thousand ohms to tens of megaohms) and internal impedance (related to the ** impedance and internal impedance of the electrocuted person). Suggestions: Pay attention to your diet, exercise more, and keep your body dry.
Obesity requires exercise. Prevents resistance from increasing.
The human body impedance is not a pure resistance and is mainly determined by the resistance of the human body. The resistance of the human body is also not a fixed value. It is generally believed that the dry ** has a fairly high resistance at low voltages, about 100,000 ohms.
When the voltage is 500 1000 volts, the resistance of the human body drops to 1000 ohms. The epidermis has such a high electrical resistance because it has no capillaries.
There is also a stratum corneum in a certain part of the finger, and the resistance value of the stratum corneum is higher, while the resistance value of the ** in the part that is not rubbed often is the smallest. **Resistance is also related to the contact area and pressure of the human body with the charged body. When the epidermis is damaged and the dermis is exposed, the body has a very low electrical resistance because it is filled with blood vessels that carry the salt solution.

The resistance of the human body is fixed and will not change with the change of the surrounding environment and voltage.

Of course, the human body has resistance! The resistance of the human body is mainly ** resistance, the resistance of the thick cuticle of the epidermis is very large, ** when dry, the resistance of the human body is about 6 10k, and even up to 100k; However, the stratum corneum is easily damaged, and the resistance of the damaged stratum corneum is about 800 1200; The resistance of the internal tissue is about 500 800.
Answer: No one. It's wrong. Any substance has its own value of resistance, and it is impossible for people to do it.
Even mercury has resistance.
People have resistors and they have a problem with the radio. It should be due to the fact that the reflection of electromagnetic waves is the same as the diffraction o, so that when he approaches the radio, the radio may suddenly be closed out or clearer. Both are possible.
I don't know if someone can talk to someone, even if the wires have resistance.
Will there be no people? Answer: Left, the resistor is not a good person, and it should be reflected.
When a person approaches the radio, it can cause problems with reception, because radio waves are a kind of wave when people are in front.
The wave produces diffraction albeit behind the person.
But if the radio is close to the first person, the radio may not receive radio waves, which is the case in only one place (e.g., there are radio waves in front of the system).
Individuals and blocks) are particularly significant, but the resistance of the person has nothing to do with whether the person approaches the radio or not.
The human body has electrical resistance.
People must have no resistance.
But there will be an electric shock. It must not be, because it was all his delusion.
Everyone's body and aging age are different, and in principle, the time of aging should be 50 years old for men and 45 years old for women.
Set up the virtual memory in this way:
For virtual memory files, Windows XP always sets the default value very large for security, which wastes a lot of hard disk space, in fact, we can set its value a little smaller. The method is to go to "Control Panel System Advanced Performance Settings Advanced Virtual Memory Change", come to the virtual memory settings window, first determine which drive letter your page files are in, and then disable all page files in other drive letters. >>>More

This score depends on your major, for example, I took the chemical engineering major, the highest score of our major was 410 (the total score was 500), and some majors, one of my classmates studied medicine, and took the Beijing Traditional Chinese Medicine exam, and their highest score was 350 points. The difficulty of the professional courses of each major is different, and this score is different. In the economics major you mentioned, one of my classmates took the Shanghai Finance and Economics exam, and last year he scored 368 points, the second in the whole major. >>>More
