Alternating current
« on: November 04, 2010, 19:38:46 pm »
This topic will be focusing on the polarity views of matter and current..
 
  Alternating current - when a point of charge is changing course from  one direction to another direction that is 180 degrees out of phase;  doing so sequentially in time.
 
  sequence is a predetermined/scaled change of phase based on time.. we call it a frequency.
 
  my point in this topic is the most talked about alternating current is that of the electron
 
  protons can as well alternate their direction of current. (path of projection) by the application of a external force..
 
  I see having 3 forces and 7 styles of applications of external forces..
 
  The forces
  1- a paddle (non stationary)
  2- voltage  (a field)
  3- light
 
  the styles
  1- paddle
  2- voltage
  3- light
  4- paddle, voltage
  5- light, voltage
  6- light, paddle
  7- paddle, voltage, light
 
  3 of the primary styles of understanding
 
  1 paddle
  Something non stationary and physical like a paddle forcing the protons into motion
  this style of force is on both the proton and electron to be influenced into the  same direction/phase the paddle is traveling
 
  2 voltage
  Something stationary having the ability to change its potential charge  within its given space " faster/less resistively"  then that of its  surrounding mediums. Different dielectric qualities between materials  in a given space will create different characteristics in the "style"  of energy transfer (current /or wave)
 
  3 paddle and voltage
  By the application of Both at the same time.. a physical force by a non  stationary object (paddle) and by a electric field (a change in the  surrounding potentials electrical charge)..
 
  1- is a force that influences both electron and proton in the "same direction"
  2- is a force that influences electrons and protons in "opposite directions"
  3- is considered 2 variables. meaning they can be in or out of tune with each other??
  there are 2 styles of generation/force happening instantaniously  forcing motion in its surrounding medium. I think to tune them you need  to know there natural tone they ring at physically and build the  circuit to match that frequency.
 
 
  i am not fully clear on lights effect (force) in a medium
 
  As for Stan his resonant cavity was stationary and applying a strong positive field.. while restricting electrons..
 
  I think he was not focusing on the oscillation (alternating) of the  electrons as much as the protons oscillations in the water.   I think  he figured out how to amplify (resonate) the proton in audio range in a  stationary gap. While influence the electrons in the opposite direction  of protons oscillation at the same time.

I think it would be wise to go over the acoustic frequency of a cylinder... After some study I have realized the frequency of a tube is not just determined by its dimensions but also the medium that surrounds the cylinder..

Since the speed of sound is dependent on the medium, the medium changes the quality of the mechanical wave (faster or slower in time)..

The frequency a tube resonates in water is 4.3 time greater then its air frequency..

This is because the speed of sound in water is 4.3 times faster

This is a mathematical in depth description of the differences of acoustical resonance  between 2 different mediums interacting with a cylinder...

speed of sound in air 343 m/s
speed of sound in water  1497 m/s at 25 °C

Measurements of interest ( resonant cavity cylinders)
Length is 4 inch's = 0.1016 meter
Diameter 1 is .5 inch dia. = .0127 meter (inner cylinder)
Diameter 2 is .75 inch = .01905 meter (outer cylinder)


Acoustical resonance of a open cylinder equation

F= nv/2(L+0.8d)

f= frequency
n=resonant node (the harmonics of the tube) it doubles the frequency more or less
v= speed of sound (is dependent upon the medium in the cylinder)
L= length in meters
d= diameter in meters


4" x .5" inner cylinder with WATER as a surrounding medium
F= 1 x 1497 / 2 (.1016 + .8 x .0127)

F= 1497 / 2 (.1016 + .01016)

F= 1497 / 2 x .11176

F= 1497 / .22352

F= 6697.4hz




4" x .5" inner cylinder with AIR as a surrounding medium

F= 1x 343.2 / 2 (.1016 + .8 x .0127)

F= 343.2 / 2 (.1016 + .01016)

F= 343.2 / 2 x .11176

F= 343.2  / .22352

F= 1535.43 hz





The difference in acoustical resonant frequency of a cylinder is based on the surrounding medium of  a cylinder and the cylinders dimensions.

Inner cylinder water and air comparison,
Fresh water = 6697.4hz acoustical resonance
Modern Air = 1535.43hz acoustical resonance
Giving a difference of 4.361
Makes sense since there is a 4.3 difference in the wave transfer speed between the 2 mediums air and water (speed of sound difference)

6697.4 / 1535.4 = 4.361



Now lets do the outer cylinder of the resonant cavity


Outer cylinder in WATER acoustical resonance frequency,

F= 1 x 1497 / 2 (.09525 + .8 x .01905)

F=1497 / 2 (.09525 + .01524)

F= 1497 / 2 x .11049

F= 1497 / .22098

F= 6774.36hz

 
Outer cylinder in air acoustical resonance frequency
F= 1 x 343.2/ 2 (.09525 + .8 x .01905)

F= 343.2 / 2 (.09525 + .01524)

F= 343.2 / 2 x.11049

F= 343.2 / .22098

F= 1553.08hz


Outer cylinder difference
Fresh water = 6774.36hz acoustical resonance
Modern Air = 1553.08hz  acoustical resonance

Inner and outer cylinder in WATER
Inner = 6697.4hz acoustical resonance
Outer =  6774.36 hz acoustical resonance
having a frequency difference of 76.96hz


Inner and Outer cylinder in AIR
Inner =  1535.43hz acoustical resonance
Outer=  1553.08hz  acoustical resonance
having a frequency difference of 17.65hz

These frequency are based off using the value 1 for the resonant node value in the equation known as n..

it is the 1st harmonic of the tube and to go into higher acoustical resonant frequencys you simply double the frequency.

This is an interesting post,but what happens to the tubes resonance when we put one inside the other?
Wouldn't the resonance now need to be the gap between the tubes?
But your results still put the frequencies in the audiable range,right where Stan says the would be.
