Can 100000w electric current electrocute a person

W is not a unit of current is a unit of power, and the unit of current is a (amperes). If it's 100,000A, it's estimated that nothing can withstand it. Because the current generates heat through the conductor, the calorific value is calculated by the formula q = current squared times resistance times time.

100000W depends on what the voltage is, if it is a civil 220V or power 380V voltage, it should be able to electrocute people, if the voltage is lower than 24V, it is not dead. However, the power of 100,000W is estimated to be 24V, and the power supply must be carried with a thick wire at the mouth of the bowl, otherwise the wire will burn out because the current is too large. I don't know if I understand enough.

What does "100000W current" mean, it is 100000A, such a large current occasion, it is generally low voltage (about 10V), and the low voltage electricity below 24V is safe and will not electrocute people, depending on how large its current is. Pay attention to the voltage!!

Electricity doesn't die, but it can burn to ashes.

Oh, the unit of current is ampere, not w, if the power of 100000w is added to the person, it must be over, and the resistance of the human body can flow through 1000000 amperes, which is almost impossible unless the ultra-high voltage is added to the human body, and it will be over.

It is related to voltage, if the voltage is very small, such as 1V, the electricity does not die.

When I was in junior high school, I first came into contact with the knowledge of electricity, and the tutorial said, 36V is the safe voltage of the human body, that is to say, this should be an accident if you add people to it, it is a person who does not die, in order to give you popular science, it is also on the bar today, how much voltage can electrocute people?

It depends on how much current it is, the TV has a high voltage of about 20,000 volts, and it may not be able to electrocute people, because its current is small. The output voltage of the welding machine is about 40V, but its current reaches tens of amperes, and the steel can also be melted, not to mention people.

Current (mA): 50Hz AC and DC.

Fingers start to feel numb and insensitive.

2 3 Fingers feel strong numbness and no sensation.

5 7. Finger muscles feel spasm, finger burning and tingling.

8 10 finger joints and palms feel pain, the hand has difficulty and disconnected from the power supply, but can still get rid of the power supply, the burning sensation increases.

20 25 The fingers feel severe pain, rapid numbness, unable to get rid of the power supply, breathlessness and burning increase, and the muscles of the hand begin to spasm.

50 80 breathing paralysis, atria begins to tremble and intense burning pain, muscles of the hand spasm, difficulty breathing.

90 100 respiratory paralysis, lasting 3min or more later, cardiac paralysis or atria stop beating, respiratory paralysis.

Taking power frequency current as an example, when a current of about 1 milliampere passes through the human body, it will produce uncomfortable feelings such as tingling; 10 30 milliampere electric current through the human body, will produce paralysis, severe pain, cramps, increased blood pressure, dyspnea and other symptoms, but usually not life-threatening; When the current reaches more than 50 mA, it will cause ventricular fibrillation and be life-threatening; A current of more than 100 milliamperes is enough to kill a person.

People often encounter static electricity that is higher than 10,000 volts;

However, because the discharge time is short, it will not cause any harm;

But if you encounter strong electricity, it will take a lot longer, and most of them will kill people.

Summary. 980,000 watts (W) is a huge amount of energy, but it cannot simply say whether it can electrocute a person, and factors such as current and time need to be considered. The sensitivity of the human body to electric current depends on factors such as the intensity of the current flowing through the body, the time of transmission, and the location of the energizing.

Under certain conditions, 980,000 watts of electrical energy can result in very high currents, which, if transmitted into the human body, can lead to electrical injuries and even death.

Summary. Hello dear and happy to answer your <>

7500w current can hurt people Oh enough to cause a serious electric shock, kiss must pay attention to prevent 7500w current can hurt people.

Kiss you and be happy to answer your <>

7500w electric Ling pure absolute flow can hurt people Oh is enough to cause a serious electric shock to the pants, kisses must pay attention to prevention

Dear, here's an extension <> for you

The human body's ability to tolerate electric current ranges from a few millimeters to a few milliamperes, and beyond this range, it will cause different degrees of electric shock damage. Therefore, if you are exposed to a 7,500-watt rapid crack flow of electric masses, it can cause serious shock injuries or even fatal. It is recommended that you avoid exposure to high-power currents and take care of safety when performing any electricity-related activities.

More than 50 milliamperes can basically electrocute a person.

The degree of harm to the human body of electric shock mainly depends on the size of the current passing through the human body and the length of time it is on. The greater the current intensity, the greater the fatal danger; The longer it lasts, the more likely it is to die.

The minimum value of current that can be perceived by a person is called the perceived current, which is 1 mA for AC and 5 mA for DC; The maximum current that a person can get rid of after an electric shock is called getting rid of the current, which is 10mA for AC and 50mA for DC; The current that is life-threatening in a relatively short period of time is called a lethal current, such as a current of 100mA passing through the human body for 1s, which can be enough to make a person fatal, so the lethal current is 50mA.

In the case of protection against electric shock, the current allowed by the human body can generally be considered as 30mA.

Measures to prevent electrocution from being delayed:

1. Safety education: vigorously publicize the safe use of electricity, strengthen the awareness of self-protection and mutual protection, and be familiar with preventive measures and safety rescue methods.

2. Strictly implement the electrical safety work process: strictly abide by the organizational and technical measures of safety production, the installation and use of electrical appliances must meet the standards, regular inspection and maintenance, promote the use of electric shock protectors, strictly prohibit private wires and dry clothes next to the wires, and cut off the power supply in case of fire.

3. Prevent electric injury caused by stepping wires: when the wires land, keep a safe distance of 4m indoors and 8m outdoors from the landing site.

4. Prevent lightning injury: during a thunderstorm, you can't work near the high-voltage Laming Li wire, don't get close to the lightning arrester, don't take shelter from the rain under the tree, don't hold an iron-handled umbrella, avoid staying on high ground, you should lie down, and cut off the external antenna at home. <>

The human body's response to electric currents:

8 10mA hands have difficulty getting rid of the electrodes and have a sharp pain (finger joints).

20 25mA hands quickly paralyzed, unable to get rid of electrodes automatically, breathing difficult.

50 80mA is difficult to breathe, and the atria begin to tremble.

90 100mA respiratory paralysis, after three seconds the heart begins to paralyze and stops beating. Regardless of the voltage, the current frequency is 30Hz 300Hz, the current through the human body reaches 50mA, and the energizing time is 1 second, which can cause death.

Voltages greater than 36V are dangerous to the human body.

According to the physiological response of the electric current when it passes through the human body and the degree of harm to the human body, the electric current can be divided into the following categories:

1. Perceptual current: the current that the human body can feel, but does not suffer damage; AC, DC 2mA.

2. Get rid of the current: the current that the human body can get rid of independently after electric shock, it is generally believed that the power frequency is less than 30mA and the DC is less than 50mA.

3. Fatal current: the current that endangers life after a human electric shock. It is generally believed that the power frequency is above 30mA and above DC, and the DC is above 50mA; But if it lasts for a long time, even if the current is as small as 8-10mA, it can be fatal.

It will electrocute people. It's 20,000 volts, 100 milliamps.

What the middle school says is generally not higher than 36v. (Of course, there is also a certain range, because different ranges of people react differently, see the following explanation for details).

The last "resistance of a few ohms" you asked is not exact, the person is subjected to the voltage and the current flowing through the person, and the resistance here refers to the resistance of the human body itself. The voltage that a person can withstand is generally called the safe voltage.

The safe voltage refers to the voltage that does not cause direct death or disability to the people of Weidongqin.

The "safe extra low voltage" that allows continuous contact under normal ambient conditions is 50 V.

The human body's response to electric currents:

8~10ma

The hand has difficulty getting rid of the electrodes, and there is a sharp pain (finger joints).

20~25ma

The hand is quickly paralyzed, does not automatically get rid of the electrodes, and has difficulty breathing.

50~80ma

Difficulty breathing, atria begin to tremble.

90~100ma

Breathing is paralyzed, and after three seconds the heart begins to paralyze and stops beating.

According to Ohm's law.

i u r) can be known about the magnitude of the current flowing through the human body, the applied voltage and the resistance of the human body.

Relate. In addition to the human body's own resistance, the human body resistance should also be attached to the human body other than clothing, shoes, pants and other resistance, although the human body resistance can generally reach 5000, however, there are many factors that affect the human body resistance, such as damp sweating, with conductivity.

Dust, increasing the contact area and pressure with the charged body, and the damp and oily stains of clothes, shoes, and socks can all reduce the resistance of the human body, so the amount of current flowing through the human body cannot be calculated in advance. Therefore, in order to determine the safety conditions, the safety current is often not used, but the safety voltage is used to estimate: under normal circumstances, that is, in the dry and electric shock risk environment, the safety voltage is specified as 36V, and for the wet and electric shock risk environment (such as metal containers, pipeline welding and maintenance), the safety voltage is specified as 12V, so that the current through the human body during electric shock can be limited to a small range of bi, which can ensure personal safety to a certain extent.

If you want to electrocute a person, you must meet one condition, and that is the time that this voltage acts on the person's body! If the voltage of 1000V continues to act on the human body for more than 3 seconds, the person will die!! Specifically, the safe voltage is 36V, and if the voltage exceeds 36V, it is possible for people to die if they continue to act on the human body!!

Of course, it's okay to go below 36v!!

Whether you can electrocute a person depends on how big the current is, and how long it takes to pass through the current, which has nothing to do with how much voltage it is. It's like a bird can stand on a high-voltage line and be fine, because the current flowing through its body is small.

However, when applied to a specific person, the high voltage and current are large, so the high voltage is more dangerous. Generally, it is safe to be below 36V in a dry environment, and it must be below 12V in bathrooms and metal containers. It is normal for a person to be electrocuted 24v in the bathroom.

Direct current is more dangerous than alternating current at the same voltage.
