AC Theory: Why is AC Called a Sine Wave?

[@e5Group]

Put simply. The best learning science and principles channel in the history of ever, and the internet! 👍👏

[@JoeRobinsonTraining]

Aw, you guys! Thanks very much for the nice comment, stay tuned for more!

[@LindaTheLearner]

Joe, the way you ported the cross-section of the generator, from your cad tool into the graphing tool was genius. Translating rotation into a waveform is difficult to visualise, but you nailed it. Your teaching is the best 🏆🙏

[@JoeRobinsonTraining]

You're too kind Linda, thank you. 😊

[@no_short_circuit]

Well done Joe, another fine explanation of a difficult concept. Pity you weren't around when I was at school, might have changed the course of history!!

[@JoeRobinsonTraining]

Glad it makes sense and is of some help. Thanks for the continued support and stay tuned for more!

[@leoleorelated]

Not bad for under 3k subs. Keep it up 👍🏾

[@JoeRobinsonTraining]

Thanks Leo, I will, stay tuned for more!

[@oldgrunger5]

brilliant as always

[@JoeRobinsonTraining]

Cheers matey, stay tuned for more!

[@prabhakar664]

Brilliant explanation. Thats what i was looking for on web and stumbled upon ur video to finally end my quest. Thanks again

[@JoeRobinsonTraining]

Great, so glad it helped! 😊

[@deniscotter525]

Very well explained, surprisingly with so many electricians out there more people haven't watched your video. Thanks for your help

[@JoeRobinsonTraining]

My pleasure Denis. Thanks for watching and commenting! 😊

[@adycee2915]

Absolutely brilliant. This visual aid & your explanation makes sense of AC & it's sine wave. Love your channel & the GSH vids. Thankyou Joe 👌

[@JoeRobinsonTraining]

You're more than welcome, I'm really glad they help out. 👍🏼

[@zgbzbiot1353]

One of the best channels on KZbin.

[@fivetwoeight528]

Teaching is a calling , and you have the gift. Brilliant class👏👏👏 Thank you.

[@joshcoupe556]

I'm an apprentice and your videos are very helpful 👌 and very well explained

[@JoeRobinsonTraining]

Good to know, thanks very much and stay tuned for more!

[@ysgurjar]

This video is precious for someone like me who knows a little bit about electricity but have to deal with it everyday handling wind turbines operations (coming from geology background). Many thanks !

[@JoeRobinsonTraining]

Really glad you found it helpful! 😃

[@brythecracker]

Excellent, spot on and clear delivery!

[@JoeRobinsonTraining]

Thanks for watching and commenting!

[@BobMellor1954]

thank you, easy to understand explanation

[@JoeRobinsonTraining]

My pleasure! 😊

[@cbarton64]

This guy is brilliant, thank you!

[@weavercattleco]

The Unit Circle ... loads of fun 😊 Honestly, I don't know how anyone can study this stuff without a solid understanding of Algebra and Trigonometry. By the way, he's changing the angle in Radians. Make sure you set your calculator to degrees 😉

[@stikndip]

If it were a sign wave, it'd be a massive thumbs up sign waving right in your face, Joe! Absolutely brilliant stuff! :o))))

[@JoeRobinsonTraining]

Ah, that's kind, thanks very much. 😊

[@jaygh8857]

Excellent video Joe. Really thoroughly explained 👏🏽👌🏽

[@JoeRobinsonTraining]

Thanks very much!

[@mukeshpatel3795]

Great explanation 👏👏👏👏👏. Love from India😊😊

[@JoeRobinsonTraining]

Thanks very much, I hope it was helpful. Stay tuned for more!

[@liampickburn]

Thank you very much. I have just started to study a HNC in Electrical Engineering and really struggle to digest some of the maths when it comes to Sine waves and Trig. Looking forward to the other video's!

[@JoeRobinsonTraining]

No worries, nice to know the videos are helping at a higher level as well. If you have any requests for videos please leave them in the comments and I'll see what I can do. Stay tuned for more... including today!

[@liampickburn]

@@JoeRobinsonTraining Hello Joe. Could you do some video's on Kirchoffs First & second laws. Thank you.

[@JoeRobinsonTraining]

I'll add it to my to do list. 👍

[@connordickens2617]

👍👍

[@amitkumarmaurya8234]

sir please best video in ac theory

[@JoeRobinsonTraining]

Thanks so much.

[@linodelcore2497]

Awesome vids! Thanks Joe, you're a natural. One question, watching the generator, would 2 sine waves be produced? ( As it looks like 2 conductors are cutting the lines of flux, one is passing through the positive end while the other through the negative).

[@the_thrill_as_himself]

I had the same question. Was hoping to find it answered.

[@Fogaata]

Thank you!

[@DavidBerlind]

This video and the one that comes before it are simply the best explanations of AC I have seen (and I dig through a lot of videos). I'm guessing the one on inductors will equally demystify that enigma in ways that other videos haven't. One question I have is about which side is opposite the hypotenuse. It seems like, visually, either side could be declared "the opposite." Why did you pick the shorter side?

[@JoeRobinsonTraining]

Wow, thanks for the feedback, much appreciated. It's not about being opposite the hypotenuse, it's about being opposite the angle formed by the hypotenuse and the x-axis.

[@DavidBerlind]

@@JoeRobinsonTraining Ah ha! Thank you! These videos really are great.

[@JoeRobinsonTraining]

My pleasure, and thanks again!

[@wasimparvez6490]

thank you sir

[@JoeRobinsonTraining]

You are welcome!

[@sadiarehman9175]

An Engineer can't be a Good Engineer unless he / she is an excellent Mathematician / Physicist

[@JoeRobinsonTraining]

Agreed!

[@omidash267]

Hi, Joe, can you provide a reference page to the complete formulas at left of this electromagnetic graphic, so I could use to explore some theoretical experiments 🤔 thx 🤖

[@tunesbombom8d442]

Hi joe thank u 4every thing you do And i want link of simulation of waveform generation and the simulation of previous video of ac producing please

[@JoeRobinsonTraining]

Thanks very much, I'll post a link on social media for my graphs at some point. Stay tuned for more content!

[@Sinforosoji]

Thank you, Joe. I love this video. Tracing one of the wires like that gives us a beautiful sine wave... but what is the other wire doing through all this? I need help to understand. Shouldn't the other wire be tracing a line as well? Is it? It seems to me that if it is, then wouldn't it cancel-out the other one by bringing the total balance to zero? Please help. Thanks!

[@jah881]

loving your videos..but why the generator spins in an anticlockwise motion as oppose to clockwise..doesnt generator spins in clockwise motion

[@BraidenRobson]

Yo where is the desmos link?

[@thomasowen6119]

how can we access this desmos link ?

[@bigdoubleu117]

Which video is the 707 relation between AC and DC?

[@gbarratt1416]

Can anyone help explain why 30° is half the peak rather than 45° being the half the peak, if 90° is the peak? Struggling to get my head around that bit. Thanks

[@JoeRobinsonTraining]

If you draw a right-angled triangle with a 30° angle you'll find the shortest side is exactly half the long side. 😍 In other words the sine is equal to the opposite over the hypotenuse. 😊

That animation must have taken some work!
