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...
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.
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.
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 :)
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 .
Please sir make more videos on electronics engineering... I love the way you teach. Everything is easy and clear concept to understand.. Thank you sir.
Thank you soo much!!!!, your videos have seriously help me to understand physics. I did not understand and it has made the gibberish of physics turn to sense, thanks a lot :)
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.
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!
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.
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 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.
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
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?

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.
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.
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.
I have 2 questions: 1) what does more coils in the primary coil do for you? 2) why are the wires often thicker in the secondary coil, and how does it help?
1) More coils in the primary means that it's a "step down" transformer. Your primary (input) voltage is higher then your secondary (output) voltage. 2) If you are outputting a lot of current, then you need thicker wires.
@@bojanb4764 But I often see that the primary coil has less and thicker wires than the secondary coils, and I don't understand why they do that. This is still used in an step up transformer, with the primary coil being the input and secondary, the output
If the primary has less turns in its coil than it’s a step up transformer. The primary will have more current going through it and that will require thicker wires to withstand that amount of current. Remember W =V•I
Thanks a lot Mr, please which is the right arrangement of this formula cos in the video given the formula during explanation it was Ns/Np=Vs/Vp in but solving you interchange it to Np/Ns=Vp/Vs 🥺relationship with voltage to number of turns?? Please
both solutions involve equations that relate the turn ratio and the voltage ratio in transformers. The first solution uses Ns/Np = Vs/Vp, while the second solution utilizes Np/Ns = Vp/Vs. These equations are crucial for understanding the behavior and calculations involving transformers Are they the same
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
Thanks dear very clear But last I did not understand How you calculate efficiency E =p out/p in × 100% 583.1/ 600 =0.971 If 0.971×100% =0.971 But you said ansure is 97 how it's come Thanks dear again for your explanation

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

What is the value of charge on primary and secondary side, are they equal on both side or different?
Wow, thanks a lot. I really understand this concept now🤗🔥🔥
the intro is fire🤣😅
Thanks dear very clear
But last I did not understand
How you calculate efficiency
E =p out/p in × 100%
583.1/ 600 =0.971
If 0.971×100% =0.971
But you said ansure is 97 how it's come
Thanks dear again for your explanation
It should have been *100 only. Not 100% hehe.
0.972x100
= 97.2%
Well explained though I'm stack on question 2 on how you came up with 200 as the number of turns? Please I need a clarity
Simply explained
to calculate input current , using I2 times V2overV1 is much easier
Well explained
