Re: Electricity tends to flow through the path of least resistance

>- Maybe it causes some chemical reactions

I would say, no maybe about it. All aspects of life are basically a chemical reaction. So to influence life, electricity may either start some reaction, stop some other reaction, or possibly in some other way, change the outcome of a chemical reaction. This stop, start, or change would most likely be proportional to the amount of electric current, all other things being equal. The limitation to this may be some minimum threshold of electric current or voltage that must first be achieved.

>- Please explain how do you know that and why it matters because i don't see how this can affect the current at the output.

This a good one. If you visit the page http://paradevices.com/ultimate_zapper_cheaply_made.html , there are 2 oscilloscope images that show how the body influences the super stabilized output. One is the image that is seen when there is no load from a human body and the second shows the shift that occurs when the human body is connected to the output. Notice how the pulse shifts below the 0 volt line. At any time that the signal is below the zero volt line, the current will be flowing the opposite direction from normal. The reason for this is that the super stabilized output uses a large capacitor to transfer the electrical signal rather than a resistor that is normally used.

>- the resistance of the body progressively decreases the voltage and consequently the pressure/wave is weaker near the negative electrode(s)

This is basically true but the body is quite complex so that there actually a number of factors that must be considered. This can be observed with a properly loaded oscilloscope. Usually, this can be achieved by placing a 1 k-ohm resistor from the probe tip to ground. While not exactly right, it will do in a pinch.

>- So you admit that the head area can't be reach with enough intensity and the pressure/wave will probably be very weak in this area.

Only if you do not use the best electrode placement. Properly using the 4 point system can significantly change the dynamics. This is why for the last 12 to 13 years, I have been advising customers to use the 4 point system.

>- better and safer to put the electrode which has the weakest pressure/wave on the feet

While this is not necessary, it may be somewhat better to have 1 foot negative and the other 3 limbs positive. However, the 3 point positive shifts the minimum pressure point close enough to the arm with the negative electrode so that there is a minimal risk or migratory problems.

While I have heard of less than a dozen cases of parasitic migration from zappers, none were using ParaZapper with the 3 point positive, 1 point negative system.
