Standing on a dry wooden bench, can a person be electrocuted if his hands touch the live wire and th

Standing on a dry wooden bench, a person who touches the live wire and the neutral wire with his hands will be electrocuted, but the damage is not great.

Electric shock refers to the flow of electric current from the human body, but it is not necessarily harmful, and usually the electric shock that everyone talks about refers to the current that is harmful enough to the human body to flow through the human body, and the person standing on the dry wooden bench contacts the live wire and the zero line with his hands respectively, and there will be a huge current flowing through, and he will definitely be electrocuted.

When a person stands on a dry wooden bench and touches the line of fire, there is also an electric current flowing through, but this is flowing into the earth through the person and the wooden bench, because the dry wooden bench is an insulator, so the current is very small and generally not harmful.

Upstairs wrong. Electric shock (two-wire electric shock).

Human electric shock is divided into single-wire electric shock and double-wire electric shock, and simple contact with the live wire will form a loop between the fire wire and the earth, which is called single-wire electric shock, which can be avoided if you stand on an insulator.

If you touch the neutral line of the live wire at the same time, a loop will be formed between the neutral line of the live wire, and then all 220 volts of voltage will be applied to the human body. Even standing on an insulator is unavoidable.

When we talk about the live wire, we often refer to the live wire of household lighting electricity, which is a kind of 220 volt, 50 Hz alternating current. The human body is a distributed capacitance, the greater the mass, the greater the distributed capacitance, and when exposed to alternating current, an electric current will be formed. The magnitude of the current formed is related to the voltage and frequency of the alternating current, as well as the distributed capacitance of the contact.

The bird will not be electrocuted because the mass is small, the distributed capacitance is too small, and the current formed is too small.

When the human body comes into contact with 220 volt household lighting live wire, there will be obvious electric anesthesia, muscle spasms, pain, fear, and the body will naturally reflexively "bounce off", which is generally not fatal in the short term, and may be fatal in the long term.

There is a voltage between the live wire and the neutral wire, and between the live wire and the earth, and if the human body touches the live wire and the neutral wire at the same time, or touches the live wire and the earth, because the human body is a conductor, there will be an electric current passing through the human body.

It's funny upstairs! Isn't it an electric shock without passing through the heart? If you put an electric current on your head, it's not an electric shock!

Besides, the current in the human body does not mean that it goes in a straight line like in a wire, telling you that as long as the wire is electrified, it will be electrocuted, but only touching the neutral wire or the live wire will not be electrocuted!

Because when we stand on an insulated stool and touch the live wire, because the human body is insulated from the earth, we have the same potential as the live wire, and there is no potential difference in the voltage will not be generated.

There is no circuit between the live wire and our body and the transformer, so there is no current passing through our body, so there is no electric shock. Let's look at the circuit diagram of a light bulb that lights up.

When a person stands on a dry stool and touches the line of fire with one hand, he has electricity in his body, and when another person stands on the ground and touches him, both of them will be electrocuted, because there is already a complete circuit with the earth.

Depending on the intensity of the current, the sensation or injury level of electric shock is also different: for the current of 5mA, only the electric shock is felt, and there is generally no harm; At 10 mA, the muscles will have fibrous twitching and may not be able to loosen the wires on their own; For a current of 100mA, a few seconds of contact is enough to be fatal; To 1a of current, the body tissues are severely burned due to overheating.

In addition, the injuries caused by electric shock are also related to the length of the contact time.

Answer: A person stands on the stool in the question and touches the fire wire with one hand, because the current does not pass through the human body, and if the current is very small, it will not be electrocuted. However, if a person standing on the ground touches him, a pathway can be formed, and an electric shock may be achieved.

A person standing on a dry stool and touching the line of fire with one hand, he will not be electrocuted, his body is already electrified, and the reason why he is not injured by electricity is that he is standing on a dry wooden bench and does not form a circuit with the earth; When another person stands on the ground and touches him, he will be electrocuted, because man is a conductor, and when another person stands on the ground and touches him, both of them will be electrocuted, because there is already a complete circuit with the earth.

To be electrocuted, there must be a circuit in the electricity, and if a person stands on a dry stool and touches the line of fire with one hand, he will not be electrocuted, because there is no circuit. There is no electricity on the body. But when another person stands on the ground and touches him, there is a circuit of electricity, and both of them are electrocuted.

First of all, your question is flawed.

A person standing on a dry stool and touching the line of fire with one hand will not be electrocuted because there is no circuit formed (a dry wooden stool is an insulator). At this time, if there is another person standing on the ground, if they are not wearing insulated shoes, those two people will be electrocuted!! (Of course, if the other person has good insulation, it should not be electrocuted).

Because the human body is electrically conductive, when it comes into contact with the line of fire, it is relatively electrically current.

The other stands on the earth, which corresponds to the zero point of the voltage. When it comes into contact with a live person, the current of the live wire will be.

It will pass through the two of them and flow back to the earth. So you will be electrocuted.

Electric shock refers to the presence of an electric current through the human body that requires a loop or grounding.

If there is a voltage and the resistance is very high (such as a dry wooden bench) does not produce an electric current, there will be no electric shock.

If one person stands on the ground and touches him, the two of them will form a contact between the voltage and the ground, forming an electric current. Both were electrocuted at the same time.

Hope it helps.

If there is no electricity, the other person will not be electrocuted if they do not touch the neutral line.

That person will be electrocuted, and the person is a conductor.

Generally speaking, it is necessary to analyze the specific problem on a case-by-case basis, of course, this behavior is a risk, so it is not recommended to try, but theoretically,If the wooden bench is absolutely insulated, then it will not be electrocuted when it hits the fire wire, of course, it is worth noting that if the body touches other obstacles, then it may become a conductor at this time, so we must be cautious, and we can also consider the problem from the following aspects. <>

1. If a person stands on an insulated wooden bench, then if he touches the fire line at this time, he will not be electrocuted, and theoretically speaking, as long as the wooden bench is sufficiently insulated, then no current will be formed at this time. In fact, for us, in a sense, if the wooden bench is an insulator, then at this time standing on the wooden bench and then touching the live wire with the load, at this time will not be electrocuted, and for us will not form an electric current on the body, so naturally there will be no risk, but do not try it easily. <>

2. Most of the time the environment in real life is complex and diverse, and because of this, we cannot represent that the wooden bench must be insulated, so this operation also has the risk of electric shock. In fact, in reality, we will find that the environment is complex and diverse, and because of this, if you easily stand on a wooden bench and touch the line of fire, then there is no doubt that there will be a risk of electric shock at this time, so we should be more cautious at this time. <>

3. There are many special scenes in life, so standing on an insulated wooden bench and touching the thermal power with a wire may also cause electric shock, so don't try it. In fact, I have to say that there are various scenes in life, and in some special scenes, standing on a wooden bench will lead to electric shock, so it is for the sake of safety that good anti-electric measures should be worn to prevent electric shock.

In fact, for us, if a person touches the live wire on an insulated wooden bench, he will not be electrocuted at this time, but only in the case of absolute theory, and the environment in real life is complex and diverse, so there is also a risk of electric shock, so don't test blindly.

Summary. According to your description, because you are standing on a chair.

The premise is that the chair must be made of wood, it is insulated. In this way, just touching a live wire will not be electrified.

But if the wood is metal, it will be electrified because it becomes a conductor.

If a person stands on a chair and touches a live wire, will he be electrocuted?

According to your description, because you are standing on a chair. The premise is that the chair must be made of wood, it is insulated. In this way, just touching a live wire will not be electrified.

But if the wood is a metal field, it will be electrocuted, because it is a conductor that is shouted.

Will standing on the chair and touching the live wire and neutral wire at the same time cause electric shock, and will the leakage protection switch trip.

If you stand in a chair and touch the live and neutral wires at the same time, of course you will be electrocuted. But it doesn't leakage, so it won't trip.

Standing on the ground and wearing shoes at the same time touching the live wire and neutral wire will it hurt people electrically, and will the leakage protection trip.

You have to stand on the ground, and not insulated shoes, for him to trip. Now, according to your description, because the chain book is not wearing insulated shoes, it is said that it will trip early.

The principle of the leakage protector is that the current flows through the human body, and returns to the source of the power supply by referring to the earth, basically there is not much current flowing through the neutral wire, and naturally, the magnetic flux generated by the phase current in the coil cannot be offset by the balance. At this time, the magnetic field force is used to make the tripping coil move, and the leakage protection is completed.

Touching a live wire at the same time is leakage and will trip, touching the live wire and neutral wire at the same time is normal electricity, will it trip if there is no leakage?

Touching a live wire at the same time is leakage and will trip, touching the live wire and neutral wire at the same time is normal electricity, will it trip if there is no leakage?

As long as you are standing on the ground. will trip. But if you're insulated, you won't trip.

This was decided based on the original draft of our leakage protector. As long as you can understand his principle, you will know when to trip and when not to jump Zaozhou.

When a person stands on the ground and is not insulated, he will jump when he touches the fire wire, and he will jump when he touches the fire wire and the neutral line, right?

You're already standing on the ground. It has formed a circuit with our earth. So if you touch the neutral line and the live wire, it will trip.

You will jump if you touch the live line alone, and you will jump if you touch the zero line alone, right?

Whether you touch a live wire alone or a neutral wire alone, our leakage protector will trip.

At the same time, if the live line and the neutral line are not insulated, they will trip, and if they are insulated, they will not jump.

That's it.

1. Theoretically, there will be no electric shock. In the event of an electric shock, there must be an electric current flowing through the body, and there must be a voltage difference. Despite touching the live wire, the current has no flow and no voltage difference. Because of this, electricians can operate with electricity.

2. Don't use physical experiments lightly, which is prone to accidents. Because the planks are not thin and thick.

1. Humidity is not.

1. The height from the ground is not.

First, it is unknown whether there is metal interspersed with.

3. Do not operate in this way until the last resort, even if you operate, check whether the above conditions are met, try to operate with one hand, avoid body series, keep a distance from the wall to avoid contact with other conductors.

Life is precious, safety is the first thing to remember. Best wishes.
