Will this be electrocuted? Under what circumstances can you be electrocuted?

Theoretically, there will be no electric shock. Because the condition of electric shock is that there is an electric current passing through the human body. According to the analysis of junior high school knowledge, the human body is regarded as a wire (the human body is a conductor), and the live wire is regarded as a power source, and there must be other conductors to connect the human body and the live wire into a closed and loop.

In both cases, there is no circuit between the human body and the fire wire, so there is no electric shock. With the analysis of high school knowledge, the condition of electric shock is that there must be an electric potential difference between the two ends of the human body. The potential of the live wire and the conductors connected to it is positive, and the potential of the earth and all conductors connected to the earth is 0.

Specifically, the human body is connected to the live wire, and the electric potential is positive, but it is not connected with 0 electric potential or negative electric potential, so there is no electric potential difference, and there is no current, and naturally there will be no electric shock.

Theoretically, yes, but don't try it. Because facts are never exactly the same as theories.

First of all, I don't recommend you to do anything, because just because theory can be proved, but not actual provability.

1.If you grasp two hands in two different places in the line of fire, you will be electrocuted, if you only grasp it with one hand, and there are other electrical appliances at work, you will also be electrocuted, because there is a potential difference, the second year of high school will learn, the same is true of the above hypothesis, if the line of fire does not work with electrical appliances, it will be fine.

2.This one is the same as the first one, but I guess the medium you're talking about can't be high, right?

1. Look at whether you grasp with one hand or two hands, if it is one hand, then there is no loop, the current cannot pass through, it will generally not be electrocuted, and if you are two hands, you will be electrocuted.

2 Because neither plastic nor rubber conducts electricity (in general), it is actually the same as one.

In both cases, it should be fine under the ordinary voltage of 220V (electricians all wear rubber shoes to work), but if it is high-voltage electricity, it may cause rubber shoes and even air to break down, so that there is a large current flowing through the human body to the earth, causing people to have electric shock accidents.

1. Yes, because it does not touch the earth, but once it falls, it will be electrocuted.

2. Maybe, if the voltage is very large. But generally not.

Possibly. It depends on how big the voltage is.

220's fine.

If it's a lot of voltage you're going to be broken down!!

Hands touching two-phase wires (at this time, the human body as a load has been electrocuted).

Leakage protector, referred to as leakage switch, leakage circuit breaker, is mainly used in the event of leakage failure of equipment and fatal danger of personal electric shock protection, with overload and short circuit protection function, can be used to protect the overload and short circuit of the line or motor, can also be used as infrequent conversion of the line under normal circumstances.

The leakage protector has high sensitivity and fast action in reacting to electric shock and leakage protection, which is incomparable to other protective appliances, such as fuses, automatic switches, etc.

Automatic switches and fuses should pass through the load current when they are normal, and their action protection value should be set to avoid the normal load current, so their main role is to cut off the interphase short circuit fault of the system.

Common electric shock accidents are generally caused by the absence of leakage protection measures and man-made paralysis.

There are no leakage protection measures: it means that whether it is a single-phase or three-phase electrical equipment to install a leakage protector, because the leakage protector is sensitive, the power supply is cut off for a short time, so as long as it can be reasonably selected and correctly installed, the use of leakage protector has an obvious effect on personal safety, preventing equipment damage and preventing fire.

Carelessness: More than 85% of a large number of electric shock accidents are caused by wrong operation and illegal operation. The main reason is that the safety education is not enough, the safety system is not strict and the safety measures are not perfect, and the quality of the operators is not high.

Common forms of electric shock are single-wire electric shock and double-wire electric shock. Single-line electric shock is also called single-phase electric shock, such as electric fan leakage accident, etc., at this time, the human body is subjected to a voltage of 220 volts, which is very dangerous. Double-wire electric shock is a two-phase electric shock, if the human body contacts any two phases of the three wires at the same time in the three-phase power supply, it will cause a two-wire electric shock accident, and the voltage added to the human body is 380 volts, which is the most dangerous.

The reason is because of the static electricity that occurs in the human body, and the reason for the electric shock when the hand touches the metal in winter is the result of the external "discharge" of static electricity in the body.

A person's electric shock is caused by an electric current, and the reason why there is an electric current is that the object in contact (such as a wire) discharges electricity to other wires or the earth, so that the current flows through the body, and when it reaches a certain current, it will die.

And the reason why there is a current flowing is because there is a voltage difference between the wire and the ground or another wire, and if there is no voltage difference, there is no voltage, and there must be no current.

Perceptual current: The smallest current that can elicit a human sensation.

Get rid of the current: the current limit value of the power supply that can get rid of the power supply by itself after being electrocuted, 10mA.

Fatal current: When an electric current passes through the human body, the ventricles of the heart cause a fibrillatory beat, and the current value of dying is 500mA.

1. Get rid of the current size:

Adult males: about 16 mA on average and about 9 mA on average.

Adult females: the average is about 9 mA and the minimum is about 9 mA.

2. The way through which the current passes through the human body.

Any way of electric current through the human body can cause death. The passage of electrical current through the heart, central nervous system (brain and spinal cord), and respiratory system is the most dangerous.

Therefore, from the left hand to the chest is the most dangerous current path, when the heart, lungs, spinal cord and other vital organs are in the circuit, which can easily cause ventricular fibrillation and central nervous system disorders and death; The route from the right hand to the foot is less dangerous, but it can cause a fall due to spasms; It is less dangerous to go from the right hand to the left hand than from the right hand to the toe; The least dangerous route of electrical current is from foot to foot, but the person who is electrocuted may fall due to spasms, causing the current to pass through the body or secondary accidents.

The human body itself transmits electricity, and wet things, including wet hands, are particularly fond of transmitting electricity, so you can't touch charged objects with wet hands. When an electric current passes through the body, it can cause great harm to the body, and at worst, it can lose life, so you have to be careful.

The advent of electricity has brought great convenience to human beings, and even our lives today are almost impossible to move without electricity. When a person touches a live wire, an electric current will pass through the human body, which is called an electric shock. When an electric current passes through the human body, it can cause varying degrees of damage to the human body and internal tissues.

There are two types of injuries: electric shock and electric injury. Electric shock refers to the relatively serious damage to internal tissues caused by electric current passing through the human body. If the electric current continues to pass through the human body, the heart, respiratory function and nervous system of the electrocuted person will be injured, and even stop breathing, and the person will die.

There is a strange phenomenon: people will be electrocuted when they touch high-voltage wires, but birds will not be electrocuted when they stand on high-voltage wires, why is this? Because the electric current does not pass through the bird's body.

See, the bird is standing on the wire with both feet at the same time, so that there is no outlet for the current, so the bird will not be electrocuted, and certainly not scorched. When a person touches a high-voltage power line, he is usually standing on an iron tower or on the ground, and the current can easily pass through because there is an outlet. Therefore, workers repairing electrical wires should wear insulated gloves on their hands, and at the same time stand on ladders that do not touch the ground, so as not to be electrocuted.

In 1746, a professor at Leiden University in Leiden in the Netherlands accidentally discovered that it was possible to put an electrified object into a glass bottle to preserve electricity. This bottle that can hold electricity is called the Leyden bottle because it was invented in the city of Leiden.
