The last time I did transformer calculations was when I was in college (electrical engineering), even then I struggle a bit. Not only did your video bring back memories, (back in the 80's), but now helps me with the collection of unknown transformers I have. Excellent tutorial video, and explained in every detail, thank you...
you did this in college!!! I am doing this in high school
Me: Mom I want to watch transformers
Mom: We have transformers at home
Transformers at home:
Underrated comment 😭
When your mom is a physics nerd.
this is the funniest thing ive read lmaooo
LMAOOO
When children play with Transformers, they often don't understand the physics problems that the toy presents. For example, many children do not realize that a Transformer that is in car form cannot turn into a robot and fly away. They also don't understand the concept of mass and how it affects transformation. For example, a child might try to transform a small car into a giant robot, not realizing that the small car would not have enough mass to support the transformation.
I am myself a teacher. After a long time I have decided to return to school to further enhance my knowledge. Your videos are exceptionally helpful for me as I live in a third world country where availability of quality teachers is slim. Can you tell me where you graduated from and what you majored in? Your thorough explanations have inspired me to follow in your footsteps.

Physics teacher, Lou Young, was recently explaining voltage, current and power calculations to her students. She started by drawing a transformer on the board. She explained that voltage is the pressure or force that makes current flow through a conductor. The higher the voltage, the more current will flow. She then explained power as the product of voltage and current. The higher the voltage and current, the greater the power.
She then showed her students how to calculate voltage, current and power using an example problem. She explained that transformers are used to increase or decrease voltage levels. The primary coil of a transformer has a high voltage while the secondary coil has a low voltage. She showed her students how to use Ohm's law to solve for voltage, current and power in a transformer circuit.
Young's explanations were very clear and concise.
The way you teach is absolutely amazing and totally understandable. THANK YOU!
Why am I discovering this amazing channel just a week before my board exams😟??
BTW Thankyou so much, this video helped me alot and guess what? you got my subscription :)
Easiest non complicated way I found to do this with your explanation was just finding the ratio and apply as needed. Learnt alot Cheers Sensei
hey future me, remember when it was 3am and you were writing this freaking out that you werent going to pass tomorrow morning? lets hope we smashed it
How did it go?
Rip. I think the test took his soul.
How'd it go
So did you smash that test?
I think the test smashed him instead bruh
The world needs to know this channel. Thank you for these really useful videos!
Good video - straight forward. I'm a teacher covering transformers via E-learning due to the Corona Virus. I'll be using your video!
Excellent, clear explanation and at a comfortable pace. Great to use as a refresher ! Well presented and easy to follow. Well done, thanks for this !

Thank you sir.
Thank you so much for making this video.. I would request you to use this format of explaining the concept first and then solving a few questions for better understanding of how can we we solve them .
I AM FROM CALI, COLOMBIA AND I FINISHED MY DEGREE IN HOUSTON, Ç COLLEGE IN A/C HEATERS AND MOTORS. IN HOUSTON, TX. AND THIS VIDEO WAS SO GRATE. THANK YOU VERY MUCH. CONGRATULATIONS.
Spent a lot of my time and money going to college to learn this and I never did because of the lack of skills from the profesor, and this video en few minutes explained it all so clearly and even with exercises.
you guys are the best on what you do. keep up the good the work.
i love you! you have saved my life!! your the only person i can follow and understand from thank you
Thanks, my teacher had given me a question with no context. It was set today and is due tomorrow. You're helping, thanks
This really helped me. Thank you!!
Clear and comprehensive - thank you. I have spent some time looking for a good video on the subject as I prepare for the Canadian amateur radio exam. This one is the best on this topic!
Wow,what a clear explanation... thank you 🥰
you are a life saver .Thanks a lot
The world's best teacher thanks
Wonderful explanation. Many thanks
U just saved my life for my mid-term exam tomorrow at college 🙌🙌 #respect
Mind blowing 👏👏🙌🙌
Thanks very much bro am nearing exams Fantastic keep it up bro
Great Tutorial, thank you very much
these are the best classes I every had omg
thanks for that my teacher have spent like 1-2 hours to explain us transformers but you just explain us only for 17:11 min Thanks
😭😭 I wish you were my teacher.... thank you really a lot .. 3days left in my final exams I was in a confusion 🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼💕💕 thanks you're amazing
Update
I love this channel everything that is causing me a little problem in physics has been solved thanks a bunch ❤️👍🏾
I have watched your videos several times before tests. You have really helped thx. Always aced the tests.
In physics, the calculation of voltage, current and power is a common problem. In many cases, these calculations can be done relatively easily, but in some situations they can be more complex. In electromagnetic problems, transformers are often used to change the voltage or current levels. In order to properly calculate the power in these situations, it is necessary to understand how transformers work and how to apply the appropriate formulas.
YOU HAVE SAVED ME SO MANY TIMES
Awesome video! Thank you!
Just wanna say you're the best
very clear tutorial. Thank you for this sir. Please keep uploading videos to help other people especially this time of pandemic where most of the students are in online class.
Two capacitors when connected in series have a combined capacitance of 5uF.
If the capacitance of one of them is 8iF
-What is the capacitance of the other ????
Please I do need a quick answer
I'm one step away to be the smartest student in my class cos of your videos
best utube channel
as always thank you so much our teacher , never failed to teach us , prepare us and educate us ,our teacher may your life be filled with happiness and smile our teacher
I am taking the board examination to become a licensed Electrical Engineer this coming September. I've been watching you Sir since I was a college student. I'll update here if I happen to pass. Wish me luck 🙏
This channel should be changed to "Engineering and theorem Analysis: A simple way to understand everything" Anyway thank you so much for always teaching me how to survive my college life. I'm an upcoming 3rd year electronics engineering student.
Wow you coldnt have explained it any better. Great job and thank you
Thank you so much for this, I always come back to this video whenever I need to freshen up this topic !! 💞
the intro is fire🤣😅
Not understanding those stuffs in School, and watching this video, stressed life, staying awake at night- one day, everything will be memories of school life.
I really wanna thank you.... bec i got i good grades in physics because of you.
Really you don't know how grateful I am
this channel is goated
We finished these lessons I really miss them now ❣️❣️❣️
I love your work!!! Very effective, and easy to comprehend! ^^
Hi JG

Thank you for the detailed explanation✊🏿✊🏿🙏🏿🙏🏿
Thank you for your simple,simple explanation!
thanks for awesome tutorial
Wow, I finally understand! Man, thanks.
Future me: didn't study till the last week and now watching this video for the main exam tomorrow. Stressed and depressed, feeling like life is meaningless, I hope you went somewhere and you're happier now, not stressing over things like you are doing now.
THANK YOU!!!!!!!!!!!!!!! you teach so well n made me understand so fast
Thank you very much , this video really helped me a lot👍👍👍👍👍👍👍
Omg this video came in clutch
Another great lecture explaining transformers! I wonder if there is a counterpart that involves capacitors?
You are saving my GPA
wow this was great to watch...thank you very much
Excellent explanation, I've a question, without connecting a load to a secondary coil or simply the out put in both step up and step down transformer which is 99% efficient, does the transformer start consuming the power? Or it only starts consuming while a load is connected?

-What is the capacitance of the other ????
Please I do need a quick answer
THANK YOU, you just saved my project last minute T^T
Thanks alot no need to get back to my notes
your videos are of great help to us welldone
Thank you very much for this..... I'm really grateful
Wow, thanks a lot. I really understand this concept now🤗🔥🔥
Hey mate you did you delete the previous video on power factor basics- real and apparent power? I needed that!!
Good and clear explanation.
thanks man my finals are coming up and need all the help i can get
You can never go wrong with this guys. #GodSent😩
Thank you very much for this video😊😊
Great as usual 👌
Brilliant explanation!
Thank you once again.
what happens if instead of 18 resistor you plug a 10ohm, or 1ohm for that matter? I believe that focusing on voltage on the output is really misleading, the transformer output current is the formula that always stands, because in the case of a 10Ohm resistor, the voltage at the output of the transformer will be different from the formulas presented in this video.
A brilliant way to explain transformers is by comparing the electrical device to the robots: when the robots are in robot form, they are little car and alot robot. When they are a car, they are little robot and alot car. Electrical transformers provide the same function as the Transformer robot's transform ability, just replacing robot and car forms with voltage and current & relative to how the coils are setup.
XD I'm actually gonna explain transformers to people like this from now on :D
Thank you, great video!
thank you so much for this video, its super useful and clear. keep it up
In Sha Allah to come back with happiness💕
physics teacher: why am i even alive
I found you today. Thank you so much!
