Will you be electrocuted if you touch the line of fire with your hands and feet next to the ground,

It will be electrocuted, if it does not directly touch the ground, it is equivalent to not forming a loop, it is an open circuit, and if it touches the ground, a loop will be formed, and the current will flow from the fire wire through the human body to the earth, resulting in electric shock (of course, because it is alternating current, the direction of the current is changing). Human hands touching the shell of the device do form a loop, but because the resistance of the ground wire itself is much smaller than that of the human body, it is equivalent to the ground wire short-circuiting the human body, so that there is almost no current flowing through the human body.

When discussing the problem of electric shock, do not regard the earth as a resistance (in fact, the resistance of the earth is very large, not infinitesimal), but as the negative pole of the power supply, and the live wire as the positive pole of the power supply.

1. When the two hands touch the fire wire and the feet touch the bottom, there is an electric potential difference between the hands and feet, so the current will pass through the human body. Hence the electrocution.

If you touch the fire wire with both hands and feet without touching the ground, you will not be electrocuted (like a bird), which is equivalent to a short circuit of the wire.

2 It is equivalent to the grounding wire equipment shell to short circuit your person.

You think of a person as a big resistor with edges and corners, and then draw a circuit diagram to see if you know it for a long time.

Note to touch the fire wire: 1 If it is a live wire of the same phase, the foot will be electrocuted when it hits the ground, not to mention touching two, touching one will also be electrocuted.

2.If the two hands are not in phase, the feet are electrocuted if they do not touch the ground, and the electric shock is very serious, the current passes directly from the heart, and it is estimated that it will hang, and if it lands, it is more serious, it is also estimated that it will be hung.

Both hands are gripping the line of fire and feet are on the ground, which can lead to an electric shock. The voltage at home can basically reach 220 volts, using alternating current, two hands accidentally touch the live wire, at this time the earth is a conductor, generating a large current, this current is enough to kill.

If there is an electric current passing through the body, and the current is relatively large, it will pose a certain threat to human life. Even if one hand touches the line of fire, but other body parts touch the ground wire or the earth, there is a risk of electric shock.

Emergency rescue for electric shock:

1. Once there is a risk of electric shock, the power supply needs to be cut off immediately. Next, use a wooden stick, which must be dry and not wet, to separate the wire from the electrocuted part. Lift the person to a ventilated area, face the sky on his back, and untie his clothes and trouser belts to let them relax.

Then observe whether there is a heartbeat, take artificial respiration, immediately take cardiopulmonary resuscitation, and the person next to you should immediately call 120 for an ambulance.

2. In the event of an electric shock, you should react quickly, do not panic, cut off the power supply first, and do not directly contact the injured person, otherwise it will cause others to suffer. If you can't cut off the power, stand on a dry wooden plank or wear insulated gloves and pick the wires apart to isolate them.

1. To put it simply, the so-called electric shock of a person is that when a person comes into contact with a charged body, the current comes out of the power supply, reaches the human body through the live conductor (such as the wire), and then flows out from the other end through the human body and returns to the power supply end. 2. From the first point of view, the result of electric shock, there must be a path that can make the current flow, which is the current circuit in electrical engineering, if the human body can ensure that only one live wire (called phase wire in electrical engineering), any other part of the body is not in contact with any conductor, that is to say, no form of current circuit is caused, then, although the voltage on the human body at this time and the voltage on the conductor are equal, because the current does not form a loop, there is no current flow on the body at this time, in this case, People will not be electrocuted, that is, they will not be electrocuted. 3. The human body touches a certain place of the conductor without electric shock, because there is no current flowing through the human body, and no current flows through the human body because there is an insulator that blocks the flow of current, for example, when a person is in a suspended state, air is an insulator, and standing on a non-conductive object, these objects are insulators; But any insulator has a level of voltage strength, and when the voltage strength exceeds the voltage strength of the insulator, the object will be covered"Breakdown"It has become a conductive conductor, and lightning can damage buildings and other phenomena, that is, the voltage intensity charged by the thunderstorm cloud has far exceeded the dielectric strength of the air and is broken down, so that the air conducts electricity and forms a discharge path.

4. From the basic knowledge of these electrical engineering, it can be analyzed that if people only contact one live wire, and do not form a current loop, then electric shock will not occur, but if two live wires are contacted, and this is two live wires of different phases in the three-phase four-wire power supply, then because there is a phase difference between the live wire and the live wire, although the voltage of its neutral point (the neutral line of the power supply or the earth and the neutral point are the same potential, so the special shock of the voltage is not visible) is the same, but still due to the existence of the phase difference and will form a current loop, then the person will still be shocked, and the intensity of this voltage is higher than the potential of a live wire to the neutral point. If two hands grasp a wire at the same time, and no part of the body is in contact with other conductors, then because the potential difference between the two hands is the same, no current loop is formed, so there will be no electric shock.

Hold a live wire in your hand if you are insulated from your other contact surfaces without electric shock.

If you are not insulated from other contact (e.g. earth) you will be electrocuted.

Concrete will be electrocuted and will not be electrocuted if it comes into contact with a wooden floor.

Either way, it will be, unless you pull the gate off the fire wire, and if it feels fine, it just means that no electricity is passing through you, which means that no other part of your body is touching the ground wire, which means that you are insulated from anything that is grounded. But you have electricity on your body, and if someone or something (not insulated from the ground) touches you, you will be struck by electricity.

1.Because there is a wire between the two hands, the resistance of the wire is less than that of the human body, so the current passes through the wire and not through the human body, and the person will not be electrocuted.

2.It is the wire in parallel between the human body and the two hands.

3.Whether or not you are electrocuted by touching it with one hand depends on where you are standing.

If there is a conductor under your feet (such as the earth), you will be electrocuted, and if it is an insulator (such as a wooden stool), you will not be electrocuted.

If another part of the body touches the conductor while one hand touches the wire, it will also be electrocuted).

Probably, if one hand touches the live wire and the soles of the feet are not insulated, you will definitely get electrocuted. As long as there is no circuit with the earth, there will be no electric shock, which means that there is no problem standing on a wooden stool. Therefore, this operation needs to be done with caution.

Electric shock is a common name for electrical injury, which usually refers to the tissue damage and dysfunction caused by the human body directly touching the power supply or high-voltage electricity passing through the human body through air or other conductive media to transmit the current through the human body, and in severe cases, cardiac and respiratory arrest occur. High voltages above 1000 V (volts) can also cause burns. Lightning damage (lightning strike) falls under the category of high-voltage electrical damage.

When the human body is exposed to electric current, the mild person immediately appears panic, sluggishness, paleness, muscle contraction at the contact site, and dizziness, tachycardia and general fatigue. In severe cases, coma, persistent convulsions, ventricular fibrillation, and arrest of heartbeat and breathing may occur. Some people with severe shocks have symptoms that are not severe at the time but suddenly worsen after 1 hour.

Therefore, the following precautions should be taken to prevent electric shock:

1. To prevent electric shock and short circuit;

Second, pay attention to the switch to control the live line;

3. It is best not to connect the fuse on the zero line;

Fourth, the center of the lampholder is connected to the fire wire;

5. Do not mix the grounding wire and the neutral wire;

Sixth, the electrical appliances are cut off, so that the electrical appliances will not be electrocuted, and if the zero line is broken, the electrical appliances will be electrocuted.

Yes. 1 If the power supply you are touching is a center-point direct grounding system, and you are standing on the ground and there is no insulation from the ground, then you will definitely be electrocuted. And if you're wearing well-insulated rubber shoes and the voltage isn't high, you probably won't get electrocuted.

However, if the voltage is relatively high, it may penetrate your rubber shoes and cause you to be electrocuted.

2 If the power supply you are touching is a system with no grounding at the center point, and you touch the live wire, since only the capacitive current flows through your body, if the capacitive current is less than 80mA, you are still safe.

3 Even if the center point is not grounded, if the system is large and the cables and wires are stretched far away, so that the capacitive current is greater than 80mA, the person who touches the fire wire will still have cardiac convulsions and die.

No! To have an electric current flowing, there needs to be a potential difference, and there is no potential difference between the two hands of the live wires that you are all touching. You stepped on the insulating stool again, and there is no electric potential difference with the earth!

There will be no electric shock because there is no loop current (one-phase live wire).

No, because an electric shock must have a large current flowing through the body. Your foot is on the insulation, proving that the current will not be footed from the hand runner. When both hands touch the live wire at the same time, the voltage difference between the hands is almost zero. So if there is no voltage, there will be no current flowing, let alone electric shock.

No, there is a stool or something underneath, as long as it is wood, it will not be electrocuted.
