Best explanation in history. I keep coming back to this video. Thank you!!

No yelling, no screaming (i.e., something something ElectroBOOM), explained in a clam incremental approach, and that's what you call a great video. Thanks, learned a lot.

Great refresher! I received my bachelor's in electrical engineering and now I'm finishing up my PhD in Comp Sci. This series is not only helping me recall all those things I used to know, but I'm also learning so many practical lessons that I didn't get from class. It's a great feeling!

Man how i hate this, as Engineering student books were the only source 20 yrs back for us. and using web sites took long time to load on 64kbps on PPP and using search like Alta Vista, AOL etc.. and now, look at this video and instructors all around the world giving easy to understand, point by point simulation and educating kids all around the world for free via videos... Great Work; loved your video and work...

I am a 71 year old man that cannot hear very well anymore, but you must have taken at least 20 speech class to do this clear and concise presentation. You are truly a gifted person when it comes to talking and presentation. I Love the fact that there is no background, so called music, or any other noise to mess up me hearing someone talk. I truly hope you make more very informative and well planned videos. I have subscribed. Thank you for taking the time to teach us!

I haven't been to electronic classes in almost 20 years and forgot everything above just the very basics. After watching many videos and looking at different sites. This has been the easiest video to understand.

Whoa! Tutorial that goes straight to the point, including coherent examples, flows perfectly, and a narration that is crisp clear. I think that you just wiped the floor with all other instructors and teachers out there. Not that you needed to. All of your videos are pure awesomeness. Thank you.

Awesome tutorial! Keep them coming, I am actually beginning to get some basic understanding of electronics, thank you so much. I am 60 and this has always been facinating to me. My thoughts are, always learn something new every day, and pass it on. This is great grandpa stuff, keep our young children's minds entertained, and they are less likely to get into trouble.

Good tutorial. Moved along fairly fast but illustrations were excellent and professional looking.

Really love your way of explaining. My engineering teacher who thought this concept couldn't get direction of current right for a diode. You are a life saver.

As a newbie hobbyist for electronics this is the excellent tutorial I ve ever seen. As a teacher I can't help stating that Not only you are an expert at converting ac to lower dc and smooting it you also do the same thing on info.As clear as possible Excellent job.

Thank you so much for this great video and superb explanations! Two thumbs up for you Afrotechmods........

got your self another subscriber dude. awesome and clear to understand video. thanks a million.

Man have no words to describe your work. Actually you are my electrical tutor!!

This is by far the best explanation I've found for begginers like me. Thank you! You clarified many of my questions. Saludos desde argentina.

Your videos are excellent. Very clear; logical progression of concepts; and very informative. Thanks!

I miss your videos. Your videos are the best on youtube. You should make more.

I have an industrial engineering background and dabbling at 56 yrs old in hobby electronics. Very nicely done video! Subscribed.

Awesome tutorial!! Nobody has explained this stuff that clearly so far!!

Very good video. It explains all the basics. Thanks.

Gonna just binge watch as many vids of yours as I can one day! Afrotechmods: the Carl Sagan of Electrical Engineering! :3 You explain concepts with such simplicity that it's amazing how complicated texts make these things seem! I salute you! Subscribed :)

Great video! As a senior in high school back in 1971, each student had to build a 12 volt power supply using the bridge rectifier. At the time I did not fully understand why a changing load would affect the output voltage. As a 1976 graduate of the USAF School of Applied Aerospace Sciences, it all became much more clear. 8-)

Thanks for taking your valuable time to share this with strangers like me. My Pops was an electrician, but he wasn't around much and when he was it wasn't exactly a learning environment, but I always wanted to learn all this stuff. I'm almost 50 now, and my Pops is gone, thank God, but I want to teach my son about this kind of stuff, so it was time for me to start learning. I've been watching your videos for about a month, and everything I've learned so far has not been bullshit, like sooooooooooo many others I've been checking out also, so I subscribed, and I hope that helps ya some. I don't have much else to give other than my sincere appreciation. I truly do, appreciate the fact that you shared this all, in a pretty not horribly boring kinda way, so Thank you Sir!!

I study electronics and information at high school, and this video taught me more about diodes than 30 hours about diodes in electronics class .

Amaizing, most vids had me lost, this was so simple and sooooooo easy to understand! U are a true master

Awesome video. Very clear and understandable. I'm currently building a dc power supply and this video helped a lot. I thought I had bridge rectifiers pretty much figured out but I never thought of it doubling the frequency. Thank you.

This is so GOOD!!! I have spend lots of time in the lab to try to figure out how it work, and you make understand the concept in just 11 minutes. Thank you so much for upload this video.

Dude, this was awesome. So simple and to the point. Makes me want to take my old arse back to school.

Awesome Tutorial i wonder if i was tought like this!!

THAT was an AWESOME VIDEO! That's the way it should be done! The video has taken up 3 pages in my notebook (I'm in the learning/tinkering phase still) and now I FULLY UNDERSTAND what a bridge rectifier is, how it's made, how to build, all the components functions through the entire wave form and its benefits and limitations when applied to various types of builds/projects and when to and not to use one! 35 minutes ago I didn't have a clue what this "bridge rectification" alien technology was or what it was all about and now I feel way smarter because of an 11:19 video that I kept rewinding parts of and taking notes. Being smarter after a video doesn't happen often while watching RU-vid! This is the gold standard of how/when/why/where electronics videos should be done. WELL DONE SIR! THANK SO YOU! YOU HAVE BEEN SUBBED! I hope the rest of your vids are just like this!

3 years of studying general electronics and that was the time i FULLY understood bridge rectifiers....... i hope I had a teacher like you back then...

good presentation

Put caps in parallel for more capacitance and it'll work (assuming their voltage rating is ok).

This video is more than 9yr old and still has more information & better explanation than most of the newer videos.

WOW!! I just stumbled across your video's... This is AWESOME!! I built an unregulated 12v power supply for an Alpine car head unit I was using in my bedroom for source (CD/Radio) back when I was 16 b/c I had no need of it anymore, and wanted to use it b/c it was small and had a remote. So I strapped it underneath a shelf, bought a transformer and bridge rectifier, cap.. soldered them together and there I had it. I've forgotten how to do most everything electronic now I'm 34. TY 4 the video!

This video was really helpful.

Excellent job. I want to ask why does not parallel diode increase the current capacity ?

When I got my first HO train set for Christmas back around 1962, when I was 8 years old, it got me interested in electricity. In school I was able to learn math and algebra easily. I started getting books from the library about electricity and started designing circuits. I now have an electronics shop in my basement and an HO train layout that goes around the basement.

Just saw this video after trying to get 9V DC out of my Train Transformer running 5-15 V AC, Wow what a great lesson. I have blown up Diodes and Regulators because i had NO Capacitors in the circuit, great tutorial. THANK YOU, D

great, quality video.

Thank you very much.. its a great tutorial... your are serving the world... I am from a small village in Tamil Nadu, India

These are among the best tutorials I've seen on youtube for any subject!

This is the best RU-vid video on Rectification I have seen so far. Clear, well edited and exactly to the point. Well done and I hope to see more videos in the future. For now I will enjoy going through the series 👍

Excellent videos! What happens when you run 2 diodes of the same type in line? Im not very good at this and at 55 Im just starting to dabble. Thank you!Also does the bridge rectifier still pulse?

**ElectroBOOM sees **07:58**** I guess it's using my patented *FULL BRIDGE RECTIFIER!!!*

52 just starting. Your videos have been an eye opener for me. more,more,more! And thank you for your time

Typed a big comment and lost it, grrrr You won me. I'd have chosen electronics for my engineering had such videos been available in my days. You make it look all so easy. Hats off to you. Please keep up the awesome work. You're better than university professors. Subscribed midway through the video. You've got me hooked.

wow. good stuff

I so need a scope....

This is one of the best instructive channels on youtube, seriously ... Thank you.

@trance183 It's often shown as trr (reverse recovery time), from which you can calculate the approximate frequency using f=1/t. There's also the diode turn on time, but this is usually insignificant compared to trr. However, you might also be limited by the diode's junction capacitance which also can allow high frequencies to pass through. In other words, you'll never be sure until you simulate/test the diode and see how it performs in your circuit. Most schottky diodes can handle 1Mhz no prob.

That's a Pendulum song!

Fun video. DC to AC?? ;)

Another excellent video, thanks for taking the time do this. I ran out of money to finish my electronic engineering degree and I'm trying to learn on my own and it really helps!

Your Video has explained this to me well. You are better than all my electronics teachers put together. Your teaching was of such a high standard, you actually made me interested in doing something as a result. Thankyou.

Okay, how do I get 12 vdc at 5amps?

Great video! Im a novice guitar effect pedal builder and want to build units with power supplies. This really clarified that process for me. Thanks for posting.

You know how long I've been arounx electronics and still didn't understand what you just explained perfectly in a few minutes! Great video! I subscribed.

You are an excellent teacher Sir. I knew some of this years ago, but this is excellent for a refresher course. Looking forward to trying out what I've learned here. Thank you

Omg, I don't know how to thank you This is the best video I've ever seen. I was looking for something like this for a while ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍

I really have to say that most of my electronic engineering professors did not explain as clearly and concisely as you have here ... this is extremely well done.

I'm Not an electrician. My dad was. He tried to teach me some stuff and the first thing he taught me was the bridge rectifier. Your explanation is spot on. I just wish I could wrap my brain around the rest of it. I guess you could call me " electron deficient".

This is amazing, I've had to work everything here out myself, and it was all accessible here!

Man you're a life saver even in 2019!

Thank you! That was awesome in every way. Seriously. Perfectly targeted; clear and direct; well produced vid.; etc etc. Much love.

Fantastic, and I think this is just what people want to see. Real-life electronics, and explained in a very informative way and indeed 'bridging' the gap in knowlege in regards especially to 'wall-warts'. You should be a teacher indeed Afro!

This very good. Fully technical in a simple straight forward way. As an old timer radio ham its nice to get a refresher course. And learn too!

After watching this tutorial and the way you explain everything is just so understanding. I ahve never made a rectifier before but with what i have just seen i can. Fantasic video, all the best ray

This is by far the best video on how to convert and handle AC to DC .

Your tutorials are absolutely excellent. You are a great teacher. I only wish you did more videos more often.

excellent presentation; perfect combination of text, diagrams, voice over narration, and videos.

I have been looking all over in UK Lancashire for hobby electron classes so I can learn about this stuff for my projects the on thing I can find is intense full time courses with qualifications and exams... I've been trying to find out how to build a PWM speed controllers for treadmill motors usually 180VDC 5amp because they are so expensive to buy. I've had to resort to reading info from the net and watching you tube videos, Knowing nothing about electronics I have found most of the information and videos I have watched really confusing... this is actually the first video I have watch that has made sense to me. Cheers

That was EXCELLENT, I have never understood it to this level of completeness. Keep up the good work!

Best explanation ever about diodes and AC DC power supply!!

Unbelievable! You have a great way of making this understandable. Love it!!!

Learned more here (about electric components and how to use them) from him than while earning my BSME. Excellent Teacher. I just subscribed !!

enjoy these video's, i went to devry electronics school many years ago and i can tell you you are a better instructor than some of the ones at devry.it could also have been my problem, i went to night school after a full day of work and it was very hard to stay awake and i did most of my studying in the laundromat washing clothes while my wife took care of the baby. keep up the videos.

Best teacher on youtube, easy to understand lessons. Awesome Channel.

I love your videos! Thank you so much for making these videos and helping me develop my interest in electronics!

I am an Electrical engineer. I've read butt load of books,listens to hours of lecture from our instructors; but this 11:20 mins lecture on diode is the best lecture in my life ever. Thanks and keep up.

Hey- That was excellent. Very well put together, and very easy to understand. It took us 2 or 3 classes, and 1 lab section to cover that same material. Thanks for the upload, and looking forward to future vids.

excellent video. An engineering student myself and I have to build one of these next week. You've got yourself a new subscriber

Clear, unambiguous graphics and explanation. Perfect.

Thank you so much. This really helped a lot. Really appreciate the clear and concise explanation with background info. perfect.

That was awesome. This was a great brush up on my knowledge from school years ago. great great tutorial. Thanks a million

This videos are so addictive. :D Thank you Afrotechmods!

I love these tutorials of yours, Afrotechmods, many thanks!

Very nice tutorial, that is one of the best explainations ive seen yet, especially with the various examples with the scope. Thanks!

Recently subbed and I am learning so much. I couldn't grasp some concepts from just reading. Your explanations are really helpful and easy to understand. Thanks!

You have good and informative videos. Please keep them coming! I like the fact that you use the oscilloscope to show the difference between each capasitor...

Sir , the best thing I did this year is finding ur channel and subscribing to it 👍.. thank u

Great Job, Thanks a lot I'll be watching this a few times, as well as your other videos. I'm teaching my little girl (7 years old) about electronics, but I need to really hone my skills. We did a flashing little Christmas tree the other day, & now she want's to make a flashing heart. When working with kids you never know what will really peak their interest, maybe it is this. But never the less I want to understand more. I'm an electrician by trade, so I have a good start. Well thanks again.

Good to see you back. We're doing diodes in electronics classes at the moment.

I think this was incredibly well done ....I almost know nothing about this stuff really But this video helped me understand A lot of things ...Very good job explaining as well .I wish all tutorial videos were this good

Excellent! Clear, concise, and 'in bite sized chunks', for our limited ability to understand the complex without an introductory education. Thanks to AFROTECHMODS we GET THAT EDUCATION! Thanks so much! Im learning what I always wanted to KNOW! Love Q-PID "SMOOTCH! N A BIG HUG!" (a girl) : )

Beautifully produced and narrated. Subscribed!

Very clear and concise. I watched probably 3 different videos with a mild level of frustration because the explanation wasn't very clear. Thanks!!

Thank you very much for this video! I've just learned more from your video than I had all year round! Honesty thank you man..

you should have a tutorial in electronics principals. you make it fun and easy. you have what it takes to teach ! thank you,
