In this electronic basics episode I will tell you all about the different kinds of power that exist. That includes true, reactive, apparent and deformed power. Along the way, I will demonstrate how reactive power gets produced and ways to counteract it. At the end you should understand that all kinds of reactive power are a problem for our power grid.

The moment you realize that GreatScott in not about letting LEDs blink in fancy patterns anymore.
There's a lot more to electronics than blinkenlights, my friend. Take the time to learn about it. You'll be glad you did. allaboutcircuits.com and a circuit simulator on Paul Falstad's site that runs in your browser will get you off to a solid start.
That circuit simulator is a revelation to me!
I love the fact that this video touched the subject of mathematics within power electronics.
Don't shy away from mathematics, it ain't boring. Most hardcore fans are either way engineers, students or technicians. You could make an entire series about practical application of mathematics, it'd attract attention.
Fantastic! 😃
But now I'm lost. 😐
This video came just in time, i am a first sem Electronics engineering student and out professor started this topic last week, if im not wrong the german words are "Scheinleistung, Wirkleistung, and Blindleistung" .
this is one of the things i love about German language, some words are very self explanatory,
Leistung means power
Schein = Apparent
Wirk = Working / Acting
Blind = Blind
Electronics engineering so so difficult but man it is fascinating, the difficult part is the flood of knowledge which is unleashed onto your brain every week. like it took 1 month from "What is a risistor" to "Phase shifted sinusoidal alternating current waveforms and fourier transformation"
Hello. I'm gonna be first year at electronic engineer. Do u study programming ?
1st time watching this: I can't understand ANYTHING!!!!
3rd time watching this: ..........OK! now I get it!
It just really shows you that with mathematics (especially when dealing with complex numbers) you have to really study these things again and again and again!
Dude! Keep up these videos you are incredible at making these formulas look 10.000.000 times more tolerable than my mathematics courses in UNI :)
That "true power" at 2:00 was so beautiful! Almost song like.
Great Scott! Make a video about "safety capacitors" and how "safe" they are
I can put it on my to do list
@@greatscottlab thanks=)
Literally great Scott😃 lol
i have a lot of old RIFA capacitors they make great smokebombs ;)
@@alexreeve lol
Thank you. Informative as always!
I am so happy you make this videos with such a high quality of info an video editting, by far the best channel of this topic, flawless explanation
All these years with electronics and now you explained this so that even I got it. Wonderful, Thank you!
Those video should be shown to student in class for fast reminder before starting a new chapter or something, very short and on point. Great job !
Best ever explanation of reactive and active power I have seen in 4 years of my engineering. Thanks a lot man :-)
Wow Scott this is really a great video on the subject. I can't wait to see more videos on these more advanced topics
This was really great video! However I must admit that I had to pause the video to think about it a few times but that is also great, it's a sign that you actually learning something new.
Thanks for really great videos, good work!
This is what power electronics is about. You really are a brilliant electronics engineer.
The way your explaining is too good. Great Job
The best video about it on the youtube! Very good job!
I'm a first year engineer and I absolutely can't wait to start learning this stuff, it's so cool to me
I just watched a video from Applied Science about Impedance, nice to see this one coming right out.
Awesome. Been a couple months since I studied this. Very nice refresher
Very helpful for my next interview 😍 thanks @Greatscott!
I know this video is kind of old, but it must be the best explanation of AC power I have ever seen online. 👏 Thank you 🙏
WOW! We're learning complex power inside of my Intro to Circuits class right now. What a coincidence.
Thanks exactly what i was waiting for. Can't wait for the next video.
This is been the bane of my existence since I began as a power electronics technician. It requires more information input than any other pay off my job.
Thanks for the video.
Great and correct information presented in a good way.
Easy for beginners .
Waiting for the next video
As always, you made an awesome and very helpful video. Thanks!!!
This was a great video, You explained it to me really well, thanks
Thanks for this video!!!
You're welcome :-)
Gastón, tú también lo ves?, este chico es un monstruo para explicar.
Thanks, this was the best explainantion of reactive power I have seen
Awesome video GreatScott!, this video is like a summary of all the topics I've seen in some of the subjects I did this year in my university. I study electronic engeeniering. It's very cool to see all the theory applied in some examples.
Pretty straight forward and intuitive for a basics video on something most people don't know about
Thanks :-)
I will have to watch this video two three times just to get all the knowledge.. Very informative video.. Thanks
Excellent video scott, thank you.
Very good video as always, lot of knowledge and most important is u made me understand it properly 😃 👌👌👌 thanks.
Keep it up 👍
I am now excited about the PFC thing
Great video man; thanks a lot!
It helped me when I realized the power factor correcting capacitor was the same as a decoupling capacitor on a IC. The capacitor provides the in-rush current needed by the inductor and absorbs the inductive spike when the voltage changes. This limits the pumping on the power line so the power company can provide more stable power and the power lines can be smaller since the in-rush is only drawn off the mains at startup.
Great Scott you great 👍👍👍
Many compliments!
Very informative ,Thank you 👍👍👍👍
That's what the great scott a full detail explanation more than knowledge
Finally understood it after a long time always seeing it in school having no idea what it is
I really liked this one.
I really appreciate these kinds of videos. Quick, concise, and informative. Reactive power is kind of a pain to understand, but I think you nailed explaining it.
On a side note, I need to get that multimeter XD.
He made a small mistake. Reactive power is not power that oscillates. The (magnitude of) reactive power is the amplitude of that oscillations. That oscillating power is called instantaneous reactive power.
Good video and good self-gift ;) Thanks for sharing !
You just taught me in one video a topic that the professors at my school couldn't teach me in weeks of lessons.
Excellent video. I felt like I was present at the University classes. :) Nice work.
Nice to see this video its informative 👌👍
You the best. Great scott
This video is fantastically clear and instructive. During your most recent QA you were right to say that maybe you should change the name. Thanks!
Lucid explanation! 😍
Awesome video! Thanks!
Great video!
This was one of the hardest courses i had to take at school (cos phi inmprovement for single phase and for 3 phase). A lot of writing and even more calculating.
Useful video 👍
I get so lost duscussing AC. I literally am more confused now...but still enjoyed the video. Will definitely have to watch a few more times.
Thanks for the video, I m waiting for PFC video.
Thanks a lot for the video
Awesome....all ur scopes and multimeter s are good
I learned that at school this year, I wonder why I didn't watch your video before but thank you anyway
Very good, thanks!!!
Medim and high voltage customers are actually charged for consumed power and power factor. I'm eager to watch your PFC video!
Hey greatscott i like your channel too much...😍😍😍😍
Can you please make a video on communication basics..
I dig this! Could you place the Electronics Basics videos in a play list? I'd like to watch them all, but it's not in a set playlist
Super helpful
Great. You explain better than my professor did.
perfect! thanks!
Took me back to college... a long time ago!!! A massive subject, phase, impedance on their own. All good stuff :) Pronunciation is a bit weird, but understandable (I am from UK)
Thank you Scott for another great vid and I really wait for your PFC video as I repair welding machines that usually contain a PFC circuitry or module which handles it.
Just a small question though: if my memory serves me correct you don't want the power factor to be exactly 1 when we are speaking traditional electric motors or circuits that has good amount of capacitance as it creates oscillation circuit, can't remember anymore why it was so bad for the powerlines and circuitry, but I do remember that you try to prevent that from happening when compensating the inductance.
your videos used to be a lot of fun, now they are more educational with a little bit of fun. we demand a lot of fun and cool projects :)
so excelent good jobs!!! 👍👍👍
Hi Scott, love this series, I found especially the Deformed component interesting, because it was never mentioned in my college courses (only True and Reactive components). However, I don't understand from your video how the higher frequencies relate to the Deformed power. Google isn't very talkative about this specific topic, but I found a paper which defines Total Harmonic Distortion as a percentage of the frequencies that are not the fundamental frequency. Is that the ratio between the apparent power and the apparent power, which doesn't take the deformed component into account (in other words, is it equal to the cosine of the angle between the P-Q plane and the apparent power vector)?
Well explained.... I really like it..
It's more easy to understand with visual observations..
Thanks :)
I looking for reactive power compensator project video using Arduino...
I hope , I'll see this next time.
Good luck..

Gut erklärt .... ich mag es wirklich ..
Mit visuellen Beobachtungen ist es einfacher zu verstehen.
Vielen Dank :)
Ich bin auf der Suche nach einem Blindleistungskompensator-Projektvideo mit Arduino ...
Ich hoffe, ich werde das nächste Mal sehen.
Viel Glück..
Nice, Thanks for sharing :-)
Thank you soo much!
Hey Scott kann nicht so gut Englisch das es reicht für den Text:
Mittlerweile verfolge ich deinen Kanal schon über 2 Jahre und deine Videos haben mir sehr bei meiner Gesellenprüfung geholfen bin zwar „Nur“ Energie und Gebäudetechniker aber wir müssen auch Spannungteiler und Brückenschaltungen berechnen.
Diese Videos haben mir besser gezeigt wie man es ausrechnen kann vorallem an einem Praktischen Beispiel
Danke und mach weiter so tolle Videos 👍
Er kann aber Deutsch.
@ Figured out GreatScott ages ago, with all that German engineering attention to detail. He could also be Swizz or Austrian?
@@Tore_Lund no, I am from Switzerland (Schwitz as we say in Swiss german) and he would have this typical dialect.
Feel like I have just been to school. BUT ITS THE WEEKEND!!!! ;-)
love that multi-meter. :)
That escalated quickly!
You are awsesome
I love your videos
Your videos taught me many concepts of electronics
Love u sir
Your fan From INDIA
Glad you like them :-)
It would be great if we could have more details on the computations you have done to find the correct capacitance value to cancel the phase shift between current and voltage ! I couldn't find it elsewhere on the internet...
reminds me of the chinese power saver video. thanks for the further explaination!
Heroic basic 🤯
Nice video
You do a better job than my teacher.
Mind blown!!! :)
Great explanation! I can just barely grasp the mathematics thanks to my current algebra class.
Hi GreatScott,
Are you going to make that PFC video?
Best regards,
Can you do a video on the consequences of reactive power on a simple H-bridge inverter?
Hello Scott!
I have a suggestion for a Electronics Basics video - Feedback system.
I know, it might be simple, but in my opinion it would be great to see a EB video about it to understand it better :) , because i quite dont know, how to make a feedback system for my future project - modified squarewave inverter by your design :)
@GreatScott!
Hello,id like to know what equipment i need to measure my moped's Led headlight example,watts,amp,and how long it takes to drain 12v battery
Really great i don't understand at three times watching 😂 not sure in the fourth tough
Terimakasih untuk penjelasan nya, begitu jelas sekali penjelasan tentang saya reaktif
would it also have the same canceling effect if the 0.18 uF capacitor is connected in series to the motor on 7:18, the cap is in parallel to the motor) ? If not, what is the value of the capacitance needed?
Do you have a playlist of all Electronics Basics videos
Transforma powa. Gold.
PF isn't that important for such low power devices. It is important in industrial scenarios; that's why they measure and charge for it!
These videos remind me so much of Electrical and Electronic Engineering classes!
Great presentation, Thank you! One thing I got from this is If a Charging mechanism is plugged in and not being used it still consumes electricity, Correct me if I'm wrong! Thanks again.
Correct
@@greatscottlab Thank you very much!!
because the switching circuit is running , something like a cellphone charger would probably cost like 3 euros per year or something
stay creative aan i wiiiill seeee u neeeeext time 😅😉👏 this is getting adicti e 👌
