The mystery of currents and Ohm's law...

[БородаНелли]

Not quite in the topic, but very curious. Friend, a video of which I quoted in the previous topic, posted a new video:

I'm not even lazy and repeated the experiment - that's right! And now here I sit thinking, and the truth is why? After all, as I know the amperage of the currents magnitude is relatively constant and quite small.

The author seems to know the answer, but I think long will drag him((

[БородаНелли]

That's the way the author has laid out a more specific video:

[youtube][/youtube]

Ohm's law there seems to be not disturbed, but curious what the amperage of the human body, is obtained tends to be permanent)) And here's another interesting point, the currents of the resistor changed its direction, and with him everything is stable... well, a rather interesting experiment.

Maybe that's it?

by Measuring the electrical resistance of the Horny layer of the epidermis, physics was incredible at first glance, the value of every square inch of skin has a resistance from several billions to hundreds of billions om! However, to obtain these results it was possible far not at once. For this young scientist, a recent graduate of the Moscow Institute of physics and technology (MIPT), and now one of the leading members of the laboratory, Ramil Musin conducted fundamental studies of the electrical properties of the skin (by the way, recently he brilliantly defended his thesis with unusual not only for MIPT title "Electrical properties of the epidermis"). He and his colleagues have unraveled the secret of the huge resistance of the RSE, and the principle of emergence of strong quasi-static fields of a person.

Their source is generated by friction triboelectric charge (from the Greek "tribo" — friction), collects on the skin, more precisely, to her LEN is as thick as two or three dozen microns. Depending on the resistance of the dielectric charge slowly, about 10 to 15 min, flows into the body.
What was the reason such a large, several hundred and even thousand times, a change in electrical resistance of the RSE? First of all, with the diffusion of water (and directly through the skin, and not through sweat glands) in the process of regulating body temperature.

How surprising, but the mechanism of biological regulation, "including" that the body can dump into the environment up to 15 watts for its thermal power in physical entities similar to the... the sweating earthenware jug filled with water and exposed under the hot sun. With only one difference: cooling moisture on the vessel is determined only by the ambient temperature, and the transportation of the liquid through the skin — tone located in the skin blood vessels. The more they are filled with blood, the evaporation rate of the moisture through the RSE. Charge, naturally, will drain faster and the electric field strength will decrease. If trace then, what is the distribution in space of the field lines, you can extract a wealth of information about the tone of the capillary network and even on the psycho-physical state of the object.

So a simple task on a clay jug and tone the capillary vessel opens a very promising path to remote electrometer control of the vital functions of both man and animals.

In other words our skin is electrostatic charge. A multimeter does not measure electrostatics like. Without the resistor it measures galvanic current body cells. When connected the resistor, then the charge flows onto the leather conductive but not electrically charged object (resistor). And it seems somehow enhances the passage of currents through the body.

I'm curious of course<

[Экко]

This is actually the only voltage galvanic effect of the electrodes and the skin

[мимоходом]

Galvanic effect occurs when there are electrodes of different metals is the electrolyte. In this case, neither the one nor the other, although the skin conventionally, the electrolyte can be called of course. But it is not the presence of the current, and that in the presence of the resistor increases the voltage, and it should be the opposite.

As I understand it, there is just the Ohm's law everything is OK (the author simply checks wit ): U=IR. But not so easy with the effect of the observed current. Opinions very much from the leads of the power supply networks to the real currents. Most interesting, this experiment demonstrated in the lectures of a University in USA...

And just with the wire.. no resistance... have not tried..?).. And imagine.. that the force of the procrastinating.. will depend on the readings..even due to excessive neural activity of the fingers..If you push harder..and saliva to moisten your fingers.. the readings dozens of times will be different..)) but this is garbage...but people on the forehead holding the iron vertically.. when nihto not seen as a man's finger licked..and forehead.. rubbed..)

What about the fact that the person is a current source... have Measured yourself with a multimeter (ground in his left hand, the second probe in the right).

DC voltage: -25..-78mV (-200mV with wet hands). As soon as I take the probes shows -25mV and gradually increases to two minutes to high -78mV. When you change the probes places the sign does not change for some reason. If you keep your hands in one place - the voltage increases all the time. If diluted in hand, drops sharply, but the stillness is growing again. Very funny stuff, weird, apparently the voltage is spent on muscular effort.

AC voltage: -9V. There is still unclear. Variable voltage re-measured after 5 minutes, we obtain-2V. And then another 20 minutes to 0V and the change does not work )) anyway where in the body can take a break... And yet shows sometimes. Maybe this is some unusual modes of the brain?

The resistance of the body: 70кОм

Current: 0mA. However it must be measured sequentially and then in parallel, and therefore shows 0
Change its internal state (internal stress) is quite impossible readings to change. For example creating internal stress throughout the body - the accumulated tension begins to fall. And even if you just stretch the muscles of the hand. Let go of the effort grows.

And still not very clear why the author is with dry hands 10mV and not growing, and I have eightfold higher than, and is constantly increasing... is There something interesting? I guess there's...

Interestingly, even with the oscilloscope to play... And to measure the electromagnetic field and electrostatics in various modes of internal States.

[мимоходом]

The there to understand yet why change probes places, and the sign of the voltage does not change. And wonder where does AC voltage, but such a strong re-call failed. I do not glitch if the device itself.

Can someone also a multimeter will measure your "ceiling" the potential for comparison? ))

[БородаНелли]

I have dry hands DC voltage: 25 to 35mV somewhere... Also does not change the sign!

[мимоходом]

That is, you plus? I got minus

[мимоходом]

Interesting point... By changing the internal state it must be, a constant voltage of +35mv. which again two minutes becomes minus, but-25mV. That is, the range remains the same, but shifted to the area plus.

It turns out an interesting thing - the positive/negative voltage of the body can be controlled via state changes. The output to positive values is accompanied by a reverse circle, and a conclusion in the negative is a direct.

[мимоходом]

A few days tried to catch again the AC voltage of the body not worked. Quite was decided that this is a bug, but... it Happened again to generate the body of the AC voltage. First, the device typically showed 0 volts AC voltage, and then shifted to 0.1 V, then 0.2 V and gradually within minutes reached 2Вольт. The black wire in the left hand, red on the tongue.

The fun started when I red wire disconnected from the body in General and never joined the multimeter not only reset to 0V, but continued for some time to increase the readings of AC voltage. Then gently for a minute with 2V readings reached 0.2 V. Then, the internal force has managed to once again increase it to 1.5 V. Then back to 0.1 V and repeat until tired. An increasing break flow of "energy" up from the bottom of the spine. While violet is cut before the eyes and lights up the center of the forehead minty cold.

The body is attached only to the ground of the multimeter (black wire between the forefinger and thumb of the left hand). By the way, any measurement in the fingers clearly felt the ripple, but if the red wire on the tongue - then there is "Batareinaya taste current". Apparently there is electrolysis, but it can occur at miniscule voltages and the enormous resistance of flesh and skin... And where does the AC voltage when you disconnected the red wire of the multimeter... And how it can be in the body... That's a mystery.

May be someone experienced electricians/communications technicians will be able to explain described? And in General - in multimeter diagram of measuring voltage - it is active or passive? The current from the batteries goes to the leads of a multimeter in measurement modes recess and tenure? And what is the frequency of the measuring recess multimeter?

[мимоходом]

Noticed a funny thing. Measurement mode - 200mV DC voltage. Keep the black probe in the left hand. Put the red probe to the center of the forehead, when the active (channel the sacrum-the head-centre of forehead outwards). Offer, but don't touch - the device shows plus 1-2 mV, but the circuit is not even closed...

Remove the red probe clear toe. Delivered to the throat - similar to the 1-2 millivolt... I Wonder what the law describes open chain of induction I guess... But can only be induced alternating currents from the variable fields... As measured by a constant - perhaps if the frequency is high... a Mystery.

[ЛИЛИЯ-Р]

passing And the man and his energy system is not closed moments system?))) the current flowing through the nerves, maybe on the way out and gives residual on the skin, and interestingly they themselves are nervous endings measure? That will show there? I was a tester for electricians checked the meridians and points of acupuncture , where the point index rises and Peeps and where by-silence))) the walls, where there are sockets and wires and beeps -it is strange, too.The walls are probably also under the current?

[мимоходом]

You are a bit do not understand ))) In the latter case, the probe does not touch the man - it turns out that there is no circuit between the device and the person, it is called an open circuit. And Ohm's law - it is for closed circuit use. By the way, man, too, the circuit is not entirely closed, but rather can be viewed as a container with a complicated electrolyte in which are immersed electrodes...

In General, when probe not a concern - must be zero, nothing in principle can not, given that the scheme of measurement of DC voltage like an active (with power) and aiming to catch can not and should not.

On the meridians tester should not beep ))) Resistance in any case, there are non-zero. Most likely touched the probes together - it squeaked

[ВладимирЖ]

Actually, no ))) a Galvanic effect occurs when there are electrodes of different metals ...

Try connecting the probe (which is connected to the free end of the resistor) to the output resistor, which is sandwiched in the hand. That's the whole focus. You can poeksperimentirovat with different metals, without the resistors.
p.s. still it is possible this resistor to vstaviti between a cord and a multimeter, and probe clamp in the first dimension.
