I know its not clear, but if you understand this you can better see the rest.
In a single dimensional world there are only three choices; Stay where you are, go forward, or go forward the other way. Electricity, at least the
kind you know, is the same way. Anode - Cathode. Polarity is absolute. You go from one to the other. DC goes one way, only. AC goes one way then
reverses direction. There is only one possible
change in direction, reversal.
But we live in a three dimensional world. Current flow, electricity, is not restricted to flowing electrons. Any charged particle will do. Moving
ions, plasma, semiconductors, etc.. are also current carrying mediums with special properties that are not limited to MASS.
Solid wire conductors, and other solid devices do not allow for mass to move except on a small scale that is insignificant. With fluids the mass can
move. If you use DC current to move mass it can only go one way in an [almost] straight line. AC will move the mass forward then reverse. Net current
flow comes to zero if potential and switching are perfectly 180 degrees out of phase.
The switched DC power supplies you have seen are simply a device for converting AC to DC. By itself you have an open circuit and the charge carriers
do nothing. You must complete the circuit before any actions happen. And when you do two wires are connected to the power supply.
With SDC you have four connections to the power supply. In the example you see that the two poles, anode and cathode, each have two connections, not
one. Each of the two coils has a connection on each end that connect to the same pole. This is switched back and forth, sort of like AC.
What happens between the two coils is not apparent at first glance, and you would need to look deeply into the dark art of electrolysis to understand.
In and Out of the electrodes flows electrons, but electrons are not flowing through the fluid medium. It is ions flowing between. One side strips off
an electron [or more]. This creates an ion. Now that the mass is charged it is attracted to its opposing polarity, the other coil. The mass moves
through the medium and when it meets the other side it gets back an electron losing its charge. Now the electrostatic forces no longer effect the
mass.
ELECTRONS DO NOT FLOW THROUGH THE WORKING PART
The effect of charge density on the ions is also not clear from simply looking. As we know, opposites attract. But what if there is not one single
opposite? With commoner electricty the charge carriers, electrons, can only see one end of the tunnel or the other. With the Third Current the charge
carriers, ions, etc.., can see everything if they exist in a fluid medium. The opposing pole is not a single point in the example. it is a wide area
of charge. At every point where the coil touches the medium electrons will either be collected or distributed. But, because of the laws of potential
and density, an equal amount of electrons will be transfered at all points along the coil, provided you have perfect conditions with the forging of
the coils and the medium itself. Assuming that it is perfect. This means that the electrons will need to flow from one end of the coil to all points
along the coil and out in an orderly fashion. But since they are all coming from the same place, the area closer to the door will have a greater
CHARGE DENSITY.
Charge density determins the path of an ion [etc..] through a fluid medium. It heads towards the effective middle of the charge. One side is stronger
than the other.
When the cycle advances the electrons go through the other door. The area of density switches to the other side of the coil. The path of the ion
[etc..] changes.
Its like if your Mom called you up and asked you to come over because she needs help. You start heading down the shortest route, the straight path.
Then your Aunt calls and says that she needs your help even more. So you take a different path. You change direction without reversing direction and
going home. Then Mom calls you back and asks who is more important. So, you change direction again, but you don't dare go back home. After a while it
might be best to turn off your phone and go home, but what good would it do? You have a phone at home....
The same thing is happening to the charge carriers. They go one way then they change direction without going back.
Now we have covered one and two dimensions. I can't start to explain how a third dimension may apply until after you wrap your head around two.
