What the HECK is a Phasor? Alternating Current Explained.

Рет қаралды 183,581

Күн бұрын

Alternating current is kind of wild. Electric charge drifting back and forth, governed by wave mechanics. But what if I told you there's a better way using imaginary numbers and the complex plane? It's called a phasor diagram.

*Side Note:* At 1:54, I say alternating voltage is used in our power grid because it's more efficient over long-distances. That's true because we can use transformers to raise the voltage up to the 100s of thousands. That drastic increase in voltage lowers the current by the same factor. Less current means less energy loss (P = I^2 R). Transformers don't work on direct voltage, so you're stuck with whatever voltage you originally generated. That voltage will have to be whatever is needed at the load (120V or 240V or 480V), not the 100s of thousands of volts that gives us good transmission efficiency.

And there are practical reasons why this matters. Some voltmeters measure true RMS while others just measure the peak voltage and assume it is sinusoidal to calculate the RMS voltage. If you have a harmonic-intensive load, you probably would want a true RMS voltmeter, rather than a standard voltmeter.

8:20 They certainly make the math a LOT simpler -- it's _really_ convenient to be able to solve a comparatively simple algebra problem rather than a differential equation. I don't even remember exactly how phasors let us do that, but I remember being _really_ grateful for them in Circuits 1 last year. Euler's formula in general has _so many_ useful applications. The one thing I don't like about bringing in complex numbers is that it's a giant pain to solve a system of equations with complex valued coefficients -- it's way less involved when there are only "real" numbers. But then if we didn't use them we'd just have to used vectors and rotation matrices instead, which are just a more complicated way of doing the same thing anyway. 🤷

The way he's explaining it is still a bit advanced. This imo is the simplest way of understanding it. Electricity like anything else needs a prime mover. In a DC circuit you have positive and negative. It's one direction. Electricity flows from positive to negative. Now AC is simply this.. switch the positive and the negative rapidly. A simple example of this would be to put a spinning magnet, so that the + and - flip very often. This is the frequency, how often something occurs, which in the USA is 60Hz (60x per second). What happens is the electrons gain the energy but instead of traveling in one direction they jiggle back and forth. The same amount of energy can be produced just in different ratios, with more uses and alot greater distances. There's alot more to it but without getting into the details or the math those are the basics. Furthermore by tweaking different values such as turning up the frequency we have discovered radio waves and more.

@@JustinL614 Thank you for your comment. Thing is AC simply don't make no sense to me whereas DC makes sense. I've no idea why that is, though. And powerplants make electric power, AC electricity and transmit through the lines, thousands of miles away. And energy of electricity is used up. And and there're transformers in between. There's no physical direct connection. DC is simpler and makes sense. But AC? Don't know what but that just don't make no sense to me.

As someone who next year is starting my degree in electrical engineering, and a fellow physics lover, this video was extremely useful and interesting! Thank you!

In physics we spent a lot more time studying waves than we did in EE so having a wave lead by 90 degrees made sense and was easy to visualize when seeing just the wave diagram. Wish I had this video when I was first learning though! This is a great way to teach it
