    You just have to ignore the existence of electron flow. Conventional current flow is all that matters, and the only people who use electron flow are those who design integrated circuits and lunatics

      It’s also useful to think of the “ground” plane as a sort of well of potential charger carriers that the conventional current model overlooks. Aside from simultaneously visualising what’s happening inside simple ICs like BJTs / MOSFETs and the circuit diagrams I’ve found it a useful way for checking for common mode noise in circuit and PCB design.

      I guess this makes me a lunatic? Don’t know until we test it;

      Someone give me an asylum makerspace to takeover!

      And ignore magnetic fields completely?

      Also chemists doing electrochemistry where the direction of electron flow is very important. You also have to deal with anode and cathode being flipped from how you expect since you are putting current in instead of taking current out.

    The current does flow from positive to negative. Electricity is not the flow of electrons - they just generate the field that the electric wave flows through. The electrons don’t actually move very far. The wave flows outside of the wire, not in it.

      Electricity is not a real-concept, it is a qualitative aspect and the elec-root is what defines that aspect. There is no such thing as electricity, to cut it short, it’s like talking about “Science”. There is the scientific method, scientific advances, natural science which is a category of academic research, but science is a broad abuse of language, same thing goes for electricity when people picture “the blue stuff that flows in wires”, it’s reductive, ignorant and meaningless when you can talk about electrical arcs if you mean the “blue stuff”, electrical current, electrical charge, electrons if you refer to the subatomic particle allowing this exchange, electrical energy is the volts per coulombs, etc.

      But there is current and in direct current, those particles flow as historically, that was the first convention for current, AC operates through frequency oscillation. Also, electromotive force is what causes the movement of electrons, the magnetic field is just a componenent and does not induce EMR and the energy generated by it is akin to mechanical “work” caused by kinetic forces. It boggles my mind how even modern electrical engineers sometimes get this wrong.

    Couldn’t you fix this by also defining electrons as positive? Imo the physicists and electrical engineers should fight it out.

    OMG-O-S-H every circuit designed with conventional current just exploded because of your revelation here.

    My friend, this is the same branch of science that got us to space with calculations assuming spherical cows.

    While we’re at it, is a compass needle’s North pole actually a South so that it points North? Or is the Earth’s North pole actually South so that the needle’s North pole points to it?

    (I know that I could look this up, I just want to confuse people.)

    Could someone explain what makes one pole negative/positive? Like, could we have named them Alice/Bob or is there a specific reason we went with +/-?

      Magnets.

      If there’s no field there’s 0, if there’s a magnetic field clockwise it makes a positive charge, if there’s a magnetic field rotating counterclockwise it makes a negative charge,

      Likewise if there’s a positive charge it makes a clockwise magnetic field and if there’s a negative charge it makes a counter clockwise field. (I may be backwards +/- clockwise/counter clockwise, something about the thumb on my left hand…, but really it’s all arbitrarily named, but the reason you just say negative or positive is that those are scalable measures, you can’t have half a Bob or 2 Alice. )

    True, but most of laws, equations etc still work and only specific fields need to adjust for this.

    Current is defined as the flow of positive charge. The fact that electrons, which are negatively charged, actually flow the opposite direction is irrelevant. The diagrams are still correct per the definition of current.

      Current is defined as the flow of positive charge.

      No.

      electric current, any movement of electric charge carriers, such as subatomic charged particles (e.g., electrons having negative charge, protons having positive charge), ions (atoms that have lost or gained one or more electrons), or holes (electron deficiencies that may be thought of as positive particles).

    Doesn’t matter in a lot of cases. Just state the flow direction and convention once and then stick with it.
