Re: Zapper question for Arthur D - which zapper frequency is better, and why

[Guest guest]

Dear Cory,

I learned this in Physics at the University of Manitoba in 1970. The standard

definition is:

" skin effect: The tendency of alternating current to flow near the surface of a

conductor, thereby restricting the current to a small part of the total

cross-sectional area and increasing the resistance to the flow of current. Note:

The skin effect is caused by the self-inductance of the conductor, which causes

an increase in the inductive reactance at high frequencies, thus forcing the

carriers, i.e., electrons, toward the surface of the conductor. At high

frequencies, the circumference is the preferred criterion for predicting

resistance than is the cross-sectional area. The depth of penetration of current

can be very small compared to the diameter. "

The questioner asks why this effect affects DC pulses, and the reason is quite

simple: a DC pulse train can be synthesized from a Fourier series of harmonic

sine waves starting at the fundamental pulse frequency, plus a DC component.

For a similar pulse amplitude and pulse shape, the DC component will be

identical for all non-zero frequencies, so differences in results will be based

on the sine wave components only.

For our Auto-Zap Professional zapper at 2500 Hz (2.5 kHz) the sine waves are

found at harmonics of 2.5 kHz [2.5, 5.0, 7.5 kHz...]. For the 30 kHz zapper they

occur at 30 kHz harmonics [30, 60, 90...]. According to the skin effect, the 2.5

kHz harmonic train will penetrate deeper than the 30 kHz harmonics by a factor

of 3.464, which is the square root of the 12:1 frequency ratio between 30 kHz

and 2.5 kHz.

In my opinion, this deeper conductive layer will result in a better current

coverage of the major blood vessels, because they usually lie deeply embedded in

the body. As a result, I expect that the white blood cells in these vessels

would be more actively stimulated by 2.5 kHz DC offset pulses than by 30 kHz.

Our testing with a local naturopath shows a significant increase in

effectiveness with fungi, with no sacrifice with other critters.

Zapper question for Arthur D,

Arthur,

I am deciding between 2 zappers, the A6 and your model for the

ability to leave it on for plate zapping. On your website you mention

the " skin effect " :

" our 2.5 kHz (2500 pulses per second...) ...Due to the " skin effect "

it can be expected to penetrate more deeply. "

I am no physicist, but in searching the topic of skin effect, I am

assuming it is based on the physics laws of " frequency-dependent

inductance and resistance. "

The problem I am having, taking that law, and applying it to the 2

different zappers, is the zapper's are not frequency waves. They are

pulsed, offset DC. Can we assume that the physics law of " skin

effect " in regular, 360 deg. wave frequencies behaves the same as

pulsed DC in a conductive medium like the body?

Thanks Arthur!

I have good news! My friend is sending me back my A3 zapper so I

don't have to buy a new one. I only have a 1000hz food zapper here

right now and don't really enjoy plate zapping with it. I find I

liked body zapping with the 30,000hz unit much better than the 1000

hz model. I appreciate the links.

I am anticipating the arrival of the purple book. Love that color.

Praise the Lord!
