Human Electrical Potential

Is it possible to measure the electric potential of human body at every position if yes how?? and by which

The only human electric potential I know of is resistance, and it does not change with body position.

The only change would be the position of the probes, which might read differently if they are reading different amounts of mass.

Are you referring to the tiny electrical impulses emitted from the brain, through the spinal cord, to the individual nerves? Yes it can be measured but it isn't easy, and WHY??? It isn't usable energy in any respect, outside of the human nervous system.

I seem to remember (and I may be wrong on this ) that from my Psychology class way back when... the human nervous system/muscular system runs on approx 0.7V.

The Human Electrical system is measured in hospitals all the time, to look at brain functions.

Of course. Why else do you think aliens anal probe their abductees?

Because it's so much fun to watch you earthers squirm and wonder what we'll do to you next. You don't think that we really get any useful data from those probes, do you?

As far as I remember, the definition of voltage is a difference between two electric potentials, so if you have a known electric potential, you can just connect one wire from the voltmeter to it, and the other to different parts of your body, and then do the math.

It should also vary with the state of that person (eg.: how clean is its skin) and what they did right before. If you rub your hand to a wool sweater you're definitely going to have more static electricity.

Also, we were taught that the human body has an average resistance of 2-1k Ohms, plus a capacitance in parallel (don't know the value of that). The resistance varies depending on where you measure it. If the heart is "in the way" (eg. from one hand to the other) it should be about three times less as opposed to the other situation (eg. from one leg to the other).

You can set a good oscilloscope up as sensitive as it will go and touch the leads to various places on your body and "see" the electricity within.

10 fF associated input resistance of 1015  with an operating

bandwidth from 1 mHz to 100 MHz. probably.

1.5 m from a wall and was surrounded by 50 Hz, but if that human eat candy before the experiment, it can go up to 1.2 mHz.

When mechanical work is performed on a body, its energy increases by the amount of work done, so the two quantities are equivalent and we can concentrate on work. The latter is the product of the force applied to the object and the distance it is displaced. From Newton's law, force is the product of mass and acceleration, and the latter is the rate of change of velocity, typically expressed in meters per second per second.

The interior of the cell has a high concentration of potassium ions, whereas sodium ions dominate on the outside. This leads to a difference in electric potential between the inside and the outside of the cell, which can amount to as much as a tenth of a volt.

Well, I still believe, that the the elctrical potential of the human body is exactly 1 volt per Amphere.

The model of the body relating to electrical potential is resistance of the skin tissue and that the human person is a capacitor. Static electricity is discharging yourself when you touch metal and you get shocked it is in the kv range. This is why you need a ground strap when working with static sensitive parts. You could measure the discharge current and through a resistor the voltage drop.
