    This was a great video. I'd just add a few things if anybody is wondering about this and wants to make a little more sense out of it:
    - "Line To Neutral" is called "star" connection or "wye" connection (or Y-connection), and "Line to Line" is called "delta connection" (and sometimes "triangle" connection).
    - Phasor is actually a complex number that represents a sine wave, assuming a concrete frequency is given. If frequency is given, only amplitude and phase shift are needed to fully describe the sine wave. This is expressed by a complex number, and in polar coordinates it's length describes the amplitude and the angle describes the phase shift. It's a nice mathematical trick to simplify computations.
    Where's the advantage? For example, adding two sine functions results in another sine function, but the math to find out this new sine wave is annoying. To easily determine what it looks like, you can just add their respective phasors as complex numbers (i.e. as vectors) and you'll get a phasor of this new sine wave. Simple, right? Of course, you have to do the annoying proof that this is true, but from then on you can enjoy simple computations.
    Using this, you can easily compute that the voltage between two lines is √3 times the "Line To Neutral" voltage - simply by subtracting one "Line To Neutral" phasor from another (subtract, because voltage is a difference between two potentials). In other words, you are subracting two vector of the same length and a 120 degrees between them. This leads to a right triangle with a 60 degree angle, and cosine of 60 is (√3)/2 -> that's how this √3 pops up.
    - Using Phasor arithmetics you can also verify that the current in the wires between two Lines will be √3 times SMALLER than the current in the single Line (the one that goes all the way from the source to your Delta connection starting point). (Amazingly, you can see that in the video, that the red dots are moving slower when "in the triangle".)
    This means, that for both connections, if the same current is drawn from each of the lines, the same power (voltage times current) is consumed. The difference is, that in the Delta connection your device will use higher voltage and smaller current internally. This makes perfect sense, right? You simply have some power coming through those individual lines and regardless of you you decide to "harvest" it, you'll get the same amount of it.
    So (I assume) this delta connection is used in devices which have components with higher resistance inside, but still want to use some serious power.
    -------
    I hope I've described it properly. I was confused about some of these things recently so I did my research and I hope this helps somebody else.

    all the same stuffed that difficult and incomplete to me when presented conceptually, they click with me so easily in your mechanical rigor

    One of the best channel that explains Physics in simple, but effective way, and using really good animations, that give necessary information. I have to check out other videos about current. I already watched a lot about quantum Physics etc. The only thing I cannot exactly understand are tensors (why are they used? I know that they're supposed to make it easier when you change the axis etc. - I simplify - But I cannot grasp exactly why). But that's not your fault. That's because I don't work with them, so I cannot apply them - and I've learned that application is the best (for me) way to understand something.

    I wonder if the wye configuration is where they got the idea for how the flux capacitor looks in Back to the Future. If you watch an animation of a DC current flowing into a central ground in the middle of a wye configuration, it looks exactly like the flux capacitor.
    And for those interested, such an animation can easily be visualized with an online circuit diagram app. Look for CircuitMod and give it a try. I have no affilliation with CircuitMod, but it's been one of the most helpful tools I've used for understanding this stuff. Short of building actual circuits yourself, it's probably the next best thing.

    Well done! I'm learning about AC circuits and the animations definitely help. Btw, what software do you use for the animations?

      Thanks. Glad my animations were helpful. I make my 3D animations with "Poser."
