I wired the circuit above a couple of days ago. The battery holder wires give the polarity red/black. Both motors ran in the way they should. There was no cancelling of the current. The batteries read around 1.5v on the meter as did the motors whilst running. Everything appeared normal apart from the fact that the two circuits had a common wire “A” to “B” with current apparently running both ways. The wire voltage at A and B read zero.
The circuit according to mainstream theory is impossible.
eevblog.com: Can current flow in opposite directions simultaneously through same wire?
The answer to your question is yes, but currents flowing in opposite directions will cancel each other out with the wire carrying the difference between the two.
The advice above is based upon argument from authority a logical fallacy.
If the two current sources cancel then how did the motors manage to run?
How do electrons behave in such a circuit?
How do they bypass electrons travelling in the opposite direction, surely they would repel each other in all directions? No flow, no motor, but it runs.
What’s going-on in the wire AB?
What is the theory for this?
reddit.com. Why can’t electricity flow both ways down a wire?
It can, just not at the same time. Imagine water running through a pipe. It can flow one way, or it can flow the other, but if it tried to go both ways at the same time it’d just cancel out and not go anywhere.
The wiring diagram above is not new, there were one or two just like it on the internet for some time. You would think that by now someone would have wired it up and tried it to see what happens? You can find the original here
reddit.com: Electrons flow from an area where there are more electrons, to an area where there are less electrons. If you wanted to make an electric circuit with only one wire going to the battery, and current flowing both to and from the battery in that one wire (which I think is what you’re asking), then you’d have to make it so that each end of the wire had both more and less electrons than the other end. Clearly this doesn’t make sense, and is impossible.
No it’s not brilliant. The wrong headed arguments above have a common factor – they assume electron theory to be correct because they were told it is correct.
The push-electron theory
answers.com Electrical current doesn’t work quite the way that you would think.
A simple way to describe electrical current is to imagine a straw filled with marbles. Each marble represents an electron. If you push an electron in one end of the straw, and the straw was full, a marble would exit the other end of the straw.
The electrons in the straw are (according to theory) all negatively charged and as such repel each other strongly. The straw cannot be full because the electrons are pushing in opposite directions. Now try to imagine what is happening in the graphic at the top of the page with marbles moving in both directions in the same straw (wire)? It’s not going to work is it?
The pull-electron theory even worse
answers.com: However, while that example gives an idea of what is going on, electricity is actually exactly the opposite of that. An electron is “pulled” out of one end of a conductor, which crates an electron “hole”. An electron next to the hole moves into that empty spot, and so on and so on. So, even though you could visualize the electricity moving through the conductor as “pushing a marble”, it’s really “pulling one out” and marbles are moving to “fill the gap”. (This is known as hole movement in electricity).
How do you get this to happen in a single conductor?
Again, this cannot happen in a single two-way conductor and what follows is the argument via unproven and unprovable theory, quantum mechanics and even neutron stars (any port in a storm) all based upon electron theory: click for reddit.com answer
A current can flow both ways through a single conductor without loss or increased resistance because electrons do not exist.
Electrons don’t move quickly enough to fill the holes.
Wiki: Electrons are the charge carriers in most metals and they follow an erratic path, bouncing from atom to atom, but generally drifting in the opposite direction of the electric field… …Typically, electric charges in solids flow slowly. For example, in a copper wire of cross-section 0.5 mm2, carrying a current of 5 A, the drift velocity of the electrons is on the order of a millimetre per second.
Wiki: The speed of this flow has multiple meanings. In everyday electrical and electronic devices, the signals or energy travel as electromagnetic waves typically on the order of 50%–99% of the speed of light, while the electrons themselves move (drift) much more slowly. The speed at which energy or signals travel down a cable is actually the speed of the electromagnetic wave traveling along (guided by) the cable. i.e. a cable is a form of a waveguide. The propagation of the wave is affected by the interaction with the material(s) in and surrounding the cable, caused by the presence of electric charge carriers (interacting with the electric field component) and magnetic dipoles (interacting with the magnetic field component)… …The energy/signal usually flows overwhelmingly outside the electric conductor of a cable; the purpose of the conductor is thus not to conduct energy, but to guide the energy-carrying wave. https://en.wikipedia.org/wiki/Speed_of_electricity
So why do we need the electron?
It gets even more confusing:
Conventional Flow versus Electron Current
So electrical engineering current flow is opposite to the physicists current flow and it doesn’t matter?
Why do we need electrons and plus and minus?
It gets even worse for transistors:
Transistor marble in a tube analogy: (a) Electrons move right in the conduction band as electrons enter tube. (b) Hole moves right in the valence band as electrons move left.
It appears the electron needs a hole (with no marble) to move into.
physics.stackexchange.com: What are “electron holes” in semiconductors?
No one at the above agrees if holes are real or just a metaphor to explain moving positive charge. This is what happens in education when the teacher is confused.
What is required here is for someone to wire-up two simple transistor circuits with a common conductor! But even this is unproductive as it will motivate physicists to support existing theory. Someone will come-up with an unprovable answer based on unprovable theories above and debunk it.
Electricity is an energy field and both energy and field are undefined by mainstream science. It flows from more to less energy (discharge). My advice to experimenters is to ignore all theory. Ignore positive and negative polarity and just think discharge. Ignore electrons and think fields and energy. Finally ignore anyone who says it cannot be done. Think for yourself.
