Transformers are Awesome! | Doc Physics

Step up, step down, step all around town. But who's buying? This video explains how transformers work.
This video introduces some ideas that are pretty tricky. For more detail, check out the videos on Power Distribution. Thanks.

[@KabooM1067]

That outro... omg XD. I wish a lot more teachers were this fun, it would be harder to NOT pay attention to them.

[@garthmartinsen9612]

Uh... but power is also equal to V*V/R. (Ohm’s Law). There is a good reason for having high voltage for long distance power distribution but I am not sure you have pointed out the correct reason. I did however, really enjoy your presentation.

[@aravindansundaram4010]

But you only use V2/R when there is uniform voltage throughout... I reckon the voltage between two transmitters are the same but the voltage between the power source and first transmitter is less than the voltage between power source and second transmitter.. So you use V2/R when voltage is same throughout as in a parallel connection in domestic circuits..

[@lordfarqward8227]

You're one of the few youtubers that don't make me fall asleep. Thank you! I learnt a lot:)

[@8Steady]

I've watched many transformer vids, but this is the first one I found that answers that question... "who's buying?". Thank you (8 years later).

[@souhardyahalder3903]

even though i am thousands miles away,my high school days were beautified by this person.

[@DrifterD]

You taught me about transformers so much better in less than 20 minutes than my lecturer who took 2 hours to teach this, without me understanding anything. *Thank youuuu*

[@user-rx5eg3sf6z]

I like the way you explain it , it shows how much you are fascinated by those lovely transformers

[@munumaconrat5886]

Thanks👨🏾‍⚖️ Mr Doc Schuster, I'm learning a lot from your KZbin Channel than I do in the classroom🙏🏾.

[@logchain70]

IVE NEVER BEEN SO JACKED UP FROM WATCHING A KZbin VIDEO ABOUT ELECTRICAL CRAP, THIS GUY SHOULD BE A PEP TALKER FOR MMA FIGHTERS WOOOOOOOOOOOOO

[@Nicolaf95]

Wow, this is the first time i actually laugh at a science teaching video, good job my friend, i subscribed!

[@MachinistDom]

Normally I fall asleep listening to recorded lectures from my University. I think they should get Doc Schuster to do all of their lecture recordings.

[@thosehumans9329]

You explain things in a way that excites and makes me want to pay attention. Thank you

[@Ketchup__now]

Seriously, of all the videos that I've watched from you, this one was the funniest. Thanks always!!

[@MikelHensley]

I'm taking courses in electronics and sought out some KZbin videos to break the monotony of reading. I greatly appreciate how you explain how Faraday's Law works with the transformers ... that was in my text but trying to read it just makes my head hurt. Your way of explaining helps a lot. Thanks!

[@ECOMMUSK]

i am a senior electrical engineer with 11 units (3 classes) left to complete and this has been more educational than anything any professor has ever taught me

[@toddmolloy311]

Because we're taught to maintain the system we currently have not improve upon it..

[@anthonyvolkman2338]

Your mother and father live in a small house with one door and no windows. I love it!

[@RoyalAnarchist]

You're pretty entertaining my dude. I appreciate these videos; they really help me review the concepts.

[@stolendata]

I love how all the maths, theory etc. lead up to simple yet very stern and decisive declaration that the power grid was never meant to heat up the countryside.

[@ernestwerbel6235]

Thank you for explaining this difficult subject making it easier to understand. Still learning!

[@sonilzaki]

The way you ended it was totally AWESOME!!

[@davidstone2405]

You are the best. We need more people like you. Thank you so much.

[@salonisingla1665]

Thank you so much for clearing up the big voltag-small current mess doc!!

[@aliciaflores5052]

Wow, a lot of enthusiasm, it made learning about transformers more fun and interesting. It was a little bit fast paced for me, but overall it was a great video!

[@ntonyproduction]

Even though english is only my second language, I was able to understand clearly what you said in this video and it really helped me out. Thank you for these informations!

[@BrassicGamer]

Dude that was freakin' awesome. I was like "I did not come here for this!!!" but in a "I came for a bike and left with a Porsche" kinda way.

[@DocSchuster]

Excellent question, dude! It's critical to note that when you use that equation for power lost in the line, V is the voltage DROP across the line. This is VERY often misunderstood. When you talk about a high-V line, you are referring to large V between the line and ground, but saying nothing about the voltage between one end and the other (hopefully the latter is small). You find V across the line by V = IR, so it is more direct to use P = I*I/R to find power loss on the line.

[@sonnykay3594]

Doc, one thing i have to say....... YOU ARE AWESOME ,,,,,Thank you again.

[@dannydsc7]

Really appreciate the enthusiasm. You're awesome.

[@ayushimahajan6931]

The most fun class ever! I could never get these transformer thingies and here I am.. almost in love with them

[@themandude20]

I love your electricity math and circuit videos, they are the best on the net. One thing to point out is, the power to feed homes in north america is 240v not 120v as most people think. It's a 3 wire system giving the option of 240v and 120v service to homes.

[@DocSchuster]

That's a super idea! I'm not sure where it would fit, but I do have so much more to say about electrical distribution. Thanks for the note, and thanks for watching.

[@aefieefnvhas]

Absolutely love your videos, Doc! Legit your number 1 fan sitting right here.

[@ingenfestbrems]

Dude you’re taking this to personal 😁

[@mrorganic13]

Me sitting on my front porch at 5 am to the brisk morning breeze answering the last question. “YES!” Boy was I disappointed .

[@thg_2728]

This video is amazing, I think I'm gonna watch more of these coz it answers basic questions and puts it into context. AND you make it very interesting lol

[@THE______TRUTH]

Man that was a awesome explanation your ability to keep my attention is unbelievable. Thumbs up!

[@jbintali9490]

Great video! Very well explained. Thank you.

[@Bluecolorfilm]

Beautiful, thanks!

[@brianjlayman]

Best voltage mic 🎤 drop I’ve ever seen .

[@leoclarkin5944]

Great refresher explanation, thx

[@xAGirlWithNoName]

I wish my teacher was like you, I had so much fun watching this video... thank you so much!

[@chadgutierrez_music]

Thanks for making it simpler! Also, I love the distribution line drawings hahaha

[@AxzenStarcraft]

Wow, this is amazingly helpful. Serious props, thank you so much.

[@saanikagupta1508]

Thank you Doc Schuster so much!!! Your way of teaching is really good!! It helped me a lot. pls make a video for rectifier, transistor and amplifier. :)

[@abdullahibrahim1767]

very good, it is a superb performance.. thanks

[@jesussaquin6266]

Beautifully explained

[@arch_engineer8773]

Residential voltage is usually 120/240V. 120V line to neutral and 240V line to line, but I digress, you did an excellent job of explaining, and you kept it interesting.

[@sienchokhs]

Way to go! The 18 minutes was over so much sooner than I expected.

[@lullabysanton2241]

big up! simple and clear!

[@ididnothingmonkey]

Thank you! Very informative video!

[@ghacrux]

I m turkish highschool student we learned about transformers in school but i have never seen transformer before ... that was fun and you are the funniest teacher EVER 😂 All i learn in school is N1/N2=V1/V2☹️

[@ACKtube-of3qf]

Thank you so much this really helped it clarified a lot and at the same time I laughed a bunch. What a nice way to learn thanks again

[@theengineeringhobbyist7109]

Your enthusiasm is awesome! Some critical feedback is that you don't go through an explanation of where the initial equations come from just some algebra on equations you just randomly pulled out of seemingly nowhere.

[@ldiazmdiaz]

One thing we also had to take into account was the transformer winding gauges (AWG) and resistance of each windings. We design these power supply (AC/DC) with an engineer and I was the Lab Technician.

[@Andrei-ds8qv]

Very very nice! thanks!

[@MatheusSilva-dragon]

Wow! Interesting! Thanks, doc!

[@harmeetbindra6978]

This video was so helpful. Thank you

[@ssp4412]

Awesome video. Thank you so much!! ^ _ ^

[@wilmeriscool]

Thank you for your lessons here in the navy we're studying circuits and these videos are way more helpful than the classes.

[@DocSchuster]

I am honored to be able to help the good people who are risking their lives for my safety and security. THANK YOU!

[@adbeellopez4792]

This was awesome! Thank you

[@JohnSmith-cy8hq]

[@roari5740]

Funny and useful... Great vids man

[@Bigbossperson]

Thank You! The best i've ever seen this explained

[@DocSchuster]

I'm happy to hear that. Thank you!

[@apathy11303]

Transformers arent awesome!!! You are awesome because you have taught me what my professor couldn't. Thanks so much!!!!

[@paarynvadgama]

Great video, love the enthusiasm, and clear explanation :)

[@yincronje9483]

This is amazing and so helpful, thank you! Im learning for my final matric exam and this has been really useful

[@ajcrowe]

Hey David! This came up on auto play after watching another video about transformers in a class I'm taking. And I said: "Hey I went to grade school with that guy!" Awesome indeed!

[@DocSchuster]

Ha! Autoplay is the refuge of the scoundrel youtube creator, you see. Although, any class with transformers in it is a great class.

[@lulasplayzin]

Thx man, I was really having trouble deducing the equation, and now it's solved! :D

[@mukeshpandya4171]

Wait, i just took the bait and the video ended with " No!" meh! Lovely video, Kids are so lucky to enjoy such educational videos FREE of cost. Felt I used 18 minutes of my time on youtube watching something worthwhile of what i learnt in my past life... enjoyed it!

[@emmang7593]

literally saved my alevel phys exam which is coming up next monday lol... also surprised that you rly drew 40 turns on the secondary coil :)

[@garyweber6413]

Your awesome man.Please make a video about why you see different core shapes and configurations.

[@delonthompson9631]

Great video

[@TheBlondie81]

Funny and educational! *thumbs up*

[@nimeshkrishnani]

doc (Y) you the man who treats the hear'er as a friend,the reason i watched and learnt,i did learn about transformers

[@DocSchuster]

Thank you! I'm glad the video was useful.

[@nimeshkrishnani]

it really was useful,you can say i managed to crack my exam the next day,due to the video XD

[@DocSchuster]

Ka-POW!

[@nimeshkrishnani]

ka POW XD thank ya so much monsieur i shall do the knowledge sharing too if i am ever that good

[@DocSchuster]

I'm sure you'll have something to share. Do it when the time is right.

[@hakimnoori627]

i come from Afghanistan. thank you very much. I undrestod more than i did in the class.

[@keithengineer4876]

Watching this video at my desk at Ameren. Didn't realize you were local. Wonderful videos. Its my last day here so you can tell my boss. I don't care.

[@DocSchuster]

+Keith Engineer HA!

[@filip2365]

Legendary...thank you :)

[@eeitacademy6975]

Nice lecture. I like it

[@remllof]

this guy is amazing, i want to like this video about 100 more times, wow

Dude that was amazing

[@eloisejeao3522]

i get it with full of fun!!! thx doc

[@HeedyeKoren]

Dude you're the funniest and a it's pure pleasure to hear ya

[@DaFratRat]

I love this.

[@DocSchuster]

Sometimes I think about how tremendously that would change our lives. Imagine!!!

[@wajihazahra2899]

Really helped, have my physics igcse exam this week

[@fatematujjohora1529]

It's really very helpful....

[@sta8hs13]

ahahahaha! I wish I could have so much fun studying by myself! awesome video, funny as hell in the end!

[@NNN-kkky]

I see the iron ring on your hand. Can't wait to get mine. though you should wear in your pinky finger

[@jamiehardie3609]

man I find u fun it I had teachers like u wen I was at school I may have be top of the class

[@hydorah]

Would be good if you could explain more about what delta phi is and how it is calculated and such like. Would be useful for someone like me who knows nothing about the mathematical side of understanding transformers!

[@jimhinkle7245]

LOL!!! Subscribed. Well done my friend, well done.

[@DocSchuster]

Jim Hinkle Happy to have you!

[@DocSchuster]

YES! The iron in the core is laminated sheets to prevent eddy currents, which would significantly heat the iron and lower transformer efficiency. You can also make cores out of nonconductive iron-ceramic suspensions for the same reason.
