Wait a minute. At 2:55 you have the formula backwards. Vout should be:
Vin*Nsecondary/Nprimary.
You are correct. I used to have an annotation explaining this but unfortunately CZcams removed annotations.
@@AfrotechmodsHes Alive! I used to watch your videos years ago as a kid and now Im studying EE in college, all because of you. Fucking legend.
Your videos are among the clearest, most helpful I've yet found on YT. Thanks for doing such a great job at instructing. Great stuff!
Even this old video is still good. Have a friend having his mind blown about how magnitism and electrical fields are almost one in the same and how you can have one without the other.
Hes never been big on wanting to get into electronics, but magnitism instead.
But this video even after all these years is still amazing. I pointed him towards this video because its still one of the best out there for a new guy.
I wish you still uploaded on youtube. See youre still active tho, making a comment 4 months ago about annotations. When I was a young lad, your videos really taught me a ton. I miss your stuff.
Not only was this explained very well and I understood it much better than any videos on transformers I watched previously, but Afrotechmods included the European voltage in the explanation. That was so thoughtful, not everyone does that and it leaves you wondering if in any given situation how would the values change. So many thanks sir. I thought I was already subscribed but I wasn't so now I have. This is a really good channel. All the best sir.
I'm a first year automotive student, and we had to go over the basics of the electrical parts in a car, they kinda explained what a transformer was but they almost always called it an ignition coil and that's about it, just like magic happened in there, thank you for clearing so much stuff up.
Completely useful, your tutorial is short, briefly describes the concept and gives examples of situations requiring a transformer. Thank you very much.
Yups This Guy is amazing Sharing the Beneficial knowledge out of the Theoretical Theory taught by teachers blindly

jamieelectricalengineering.blogspot.com Easy to understand
I really like this video. I've been spending the last week or two researching transformers for a project that I'm working on. I definitely plan watching this video again before I wire everything up
Thank you for this video, nine years later and it's still useful!
The best narrative for a tutorial i have ever heard. Good job man. Keep it up.
Seriously. Why couldn't they have just spelled things out like this in school? So much easier to understand. Thanks for the video!
Julia Kropp I like your channel description.
true
yep it is pretty serious :/
You are more attentive now ;)
Yet again, a complete masterpiece ... superb!
The best video I've watched on the subject. Clear voice, excellent use of illustrations and pictures. Video shoots and pictures have good lighting. All around great informative video, I learned a lot. thank you very much.
Thank you so much! Been in world of confusion and this cleared it up for me! Beautiful tutorial, wealth of practical information, excellent storytelling. Keep it up.
Great little vid on transformers. Thanks. Love the humor you inject into your vids.
Excellent, when you gave guidance to volt amps , power factor , it warmed my hart .
This guy is the best on you-tube when it comes to electronic tutorials!!!
The Best you tube video I ever watched. I think it's my luck that I chanced upon your channel. Thank you very much. It's thorough, informative, accurate and occasionally entertaining in your inimitable style.
There is an easy way to avoid fatalities. Connect incadescent bulb with power similar to power of transformer inline with primary. No load, all good - small current flowing, bulb is not glowing; something wrong (shorted windings, etc) bulb will light up and limit current to safe value. Works like a charm
I love your videos! A great topic to do next would be ballasts. How to control amps, how to know number of coil turns, difference between magnetic and electrical ballast, and how to choose a ballast for a project.
+Afrotechmods Your sense of humor is awesome!
You should be an electronics teacher you are great at explaining stuff and very helpful and this is the only video on youtube that is very explanitory and legit
I been trying to figure out for hours how current flows in a transformer, and if it has negative return. All these nerds making it more complicated than it actually is. This video answered my question, finally
Great tutorial and entertainment. I'm an engineering student and found it really insightful.
Another very informative, easy to understand and useful video: thanks again!
Finally. I am starting to understand. Your video is really helpful.
Afrotechmods, another great electronics video, Very well done.
Awesome videos man! So glad I subscribed, just getting into electronics now and it's easy to feel overwhelmed
This is a really nice explanation. Thanks. I plan to direct people to this video so they understand transformers better. Nicely done!
Thanks so much for all your videos. I'm studying engineering and they assume so much of this stuff is already understood or they just sort of breeze over it. I still barely know what voltage/current actually is and I'm in third year. These are really helpful and make the basics actually really clear. Thanks
You're not alone. Very few people other than those with degrees in electronic engineering or quantum physics know what current is.
afrotech mods is the shit!!! i've been going to your site since before youtube existed! glad you're making vids again, they help a ton
Great sense of humor. I've taken a basic electronics class in college this semester. We touched on this stuff but didn't go into depth on the subject. I want to learn more about electric theory like this and motors and stuff. hanks big time for posting this! :-)
@Afrotechmods thanks! Your the man, I have learned tons from you, and I truly appreciate it! Merry Xmas
All of your videos are great, I find they are very helpful.
I always wanted teacher like you to teach me electric and electronics during my graduation studies.
Informative with some humor thrown in, very effective!
Great videos, wish you could continue with them! Thanks for the knowledge and the entertainment!
Very nice. Nobody else has really explained CT. Thanks!
Excellent introductory video, covers most need it stuff, now it's time to make a video about explaining 1 phase and 3 phase transformers and their useful applications in the world of commercial and Industrial for those interested in related Jobs !! thanks a bunch Sir !!!
I liked this tutorial, After watching your video I connected the transformer and as expected it is working well
Ever since I was a kit transformers had always been a mystery to me! Thank you for the explanation! I got smarter now! ***I subscribed***
This is the future of schooling.
seriously haha nothing like a good laugh while learning science
Ivan Vargas
It is.
I'm about to graduate with a degree in electrical engineering and I learn more from the internet than I do from the majority of my professors.
Ivan Vargas
The question after that then becomes - what am I paying them for? The paper?
Poliphodiles UniteI U Couldn't be more correct.
Man this is all too familiar to me. I think youtube should be stamped onto my degree somewhere.
Really good information. I am a fan of this kind of learning.
I like your videos. You do a good job explaining your circuitry. I took a transformer out of a broken portable cd player. I had planned on using it to provide power for a 12 V DC Car stereo to use in my garage for music. After removing it and bench testing it I found much to my surprise that it takes 120 v AC down to 12 V AC not the DC power I had hoped to obtain. So now I have to figure out how to convert it to 12 V DC . Thanks for your videos I enjoy challenge of figuring out how to make and repair my own electronics.
Best explaination i could find, even the only one that i could understand. good job and thanks! :-)
Dude you make this so much easier to understand
Fantastic, good narration and fun to watch. Will watch some of the rest as well
That was an amazing tutorial very clear explanations thankyou
Our so called lecturers need to watch these videos.
That ending tho, lol. Great video, I'm now confident enough to build my ac to dc converter.
I would like to thank you for this awesome tutorials you have. i´ve learn more of your videos here in a matter of an hour than i have i weeks. You explain things in a way that makes people understand. i´m new to electronics and you´ve thaught me much, thank you. You should teach or something hehe! Keep up the good work =)
Your videos are brilliant by the way!
This was very informative. Much appreciated
Afrotechmods, MARRY ME?!
I love your videos.
And I thought I knew about center tapped transformers, ha, ha. I learned something by watching this video. Thanks for posting. I have a very similar transformer that I want to use for a power supply, but it is not center tapped on the secondary. It does put out around 24 volts AC on the secondary, but I need to get it to 12 volts. Guess I'll have to keep watching your videos until I find my answer.
EXCELLENT INFORMATION with a touch of humour as always.
I hope you are teaching professionally. You are a natural. Thank you for the videos.
You are the transformer god! Thanks for making an idiot proof intro to transformer basics. I am 45 years old and getting back into microphone design...it has been a long time since high school electronics class.
best voice tutorials on the planet xD
Awesome explaining. I really want to know how to calculate a small transformer.
dude your so awsome i wish i knew as much as you do respect keep making video though it makes way more sense than it does in class lol
Great video. I watched the whole thing and that's a complement in itself.
I'm an educator and I will probably show the children. They'll enjoy the language.
I'm in Australia but it will translate ok
awesome videos man.. love all of them! great channel :D
@spelunkerd That's actually a clever observation on your part. The answer is that the primary side of a properly designed transformer will have a certain amount of inductance. At the AC frequency it is used at, this guarantees a minimum input impedance of the transformer. In simpler terms, the primary side of the transformer acts like a high value "AC resistor". That's why I mentioned that transformer design based on turns ratio is BS. You have to have a minimum impedance on the primary or POW!
Absolutely the best! Hilarious and REALLY informative!
Your videos are awesome! Thank you! Could you do a video on how to wire transformers in parallel and series and what it does?
fun with learning...i am a new to your channel ...thanks bro...
mr afro explains very well!!! Just i need to step up fromm 12Vto 240V.
Thanks for really informative, funny and interesting video! Love your humor! :-)
Thanks for the thoughts you have shared here.
Hi there, i've been following your vids for few months now, learned alot already!
I have a transformer from a old ZMC amplifier and it has 4 wires on the primary(Y,B BK,W) and 5 on the secondary(2R,2B and 1BK) now i get about 10.2ohm on the yellow and blue, 8.8ohm on the white and black..
On the secondary, common black with red wires both have 1.1ohm, black to blue gets infinite, blue to blue 1.3ohm and red to red 1.6ohm..
My power line oscillates between 248/252V and 50Hz..
Did you ever do the follow up dual power video? Would really like to see that as I am making a 12v dual regulated power at the moment. 👍
Afro: I subscribed to your channel. Thank you and Peace.
Very interesting and easy to understand videos. I built a car battery charger from a schematic I found online. The electrolytic capacitor exploded because I may have miscalculated the working volts (WV). I bought the parts from Jameco too. The electrolytic capacitor is the brand made in China known as SC. I think it means South China. I read reviews about their quality and some say they are unreliable. I bought two just in case, but I ordered a larger one at higher Working Volts.
Thanks from sunny California.
@eltechnic0 The scope's ground clip has a direct connection to the earth wire of your home's wiring. You could potentially short the live wire to earth, or the neutral wire to earth (which wouldn't be as bad, but the neutral wire often has a different potential than earth)
Thank you so much, very helpful easy video!
You sir are a scholar! Thank you.
@spelunkerd With almost any power source, the load determines the current that is drawn. For a simple DC example, low resistance means higher current draw.
Awesome Video Dude & Fantastic Explanation Of How To Use A Transformer. By the way it was "Bennett" that got killed by the Transformer in Commando and not "Sully" because he ("Said Sully You know I Said I Would Kill You Last...! I Lied...! As Arnie Then Dropped Him Off The Cliff") LOL. Such an Awesome Film...! Keep up the great work Dude. Nick.
+Nicholas Aarons (Nick Mini) I know, worst mistake I have ever made :( I deserve to be impaled on a steam pipe.
Cyrstal clear summarize of the transformers!
11:02 Removing any wire clippers from the area is the best! :)
Didn't expect swearing, but I like it! Subscribed! :D
Awesome tutorial!
Most of my transformers are step-up since I use and build tube circuits. The most common are between 300-0-300 (600vct) to 450-0-450 (900vct) secondary with 5 and 6.3 volt heater/filament windings for use with full wave rectifier tubes, such as a 5Y3, 5U4G, or 5AR4 type.
your videos save me from 12H reading lecturer's note and internet references. Cheers mate.
Thank you. Very educational.
so whats your favorite kind of transformer Afrotechmods ? step up, step down, autobot or decepticon?
jophable dad jokes but I’m laughing hard 😅👍🏻
@Afrotechmods OK, I think I understand this. At the AC frequency used, impedance of the transformer is designed to be very high, unless the secondary circuit is complete. I guess like a 'magnetic resistance' to current flow, not really a switch. When the secondary circuit is complete, that same energy goes into moving electrons around the secondary circuit and so primary impedance drops and current flows. The design of these little devices is more complex than I considered. Thank you!
Exactly what I needed to know Liked and Subbed.
Great channel. Thanks for your work, that comes free to me.
subscribed, liked. Thank you again.
very informative. subscribed. Thanks.
Great to see you back and doing another fantastic (and fun) tutorial.
Divide that mofo!
Also a great tip, remove any cats from the area. That's very important!
Can't say I've yet seen anything so informative on transformers yet.
Thanks much!
I like the part where he says "Now if you want to actually build stuff, that's all BS!" haha your videos are awesome...educational and funny!
easy, simple, clear, thank you so much it was helpfull for non- English mother tongue
@MrWil513 Because voltage is all relative. If the cap is between 0V and -18V, the 0V wire is more positive than the -18V one, so the positive side of the cap should connect to 0V and vice versa.
I just realized something... Your output of the 12v- 0 - 12v center tap works the same way as a 120/240 single phase Edison done in houses in North America... people keep getting confused that it's 2 phase lol.. But this is a perfect example of that system (120/240 single phase Edison).. Cool...
Yes, after looking there was a 50 ohm primary and a 2.5 ohm secondary for stepping down voltage, so I sent my signal through the secondary and had the 50 ohm primary set for output, same impedance as my antennas I was connecting to it, but I might need to amplify the signal just a bit before sending it through the transformer for output. It cleaned up the audio quality quite a bit on the output.
very nice video , lot of thanks
very nice explanation sir love from india
AfroTech, any chance of expanding this subject into inverter technology and their relationship with transformers?....
Another great Vid, btw
You are very helpful. Thanks for sharing.
Great job.
