Can you explain why half coil has more amps than the hole coil

I don't know if you read through comment, but thank you so much for educating me on how to interpret and wire transformers for 480v and 240v on the primary. I have an industrial machine at home I bought from my job and it was wired to 480v 3 phase and now that I finally have installed the machines to run at 240v 3 phase I realized I need to rewire the transformer to step down from 240v 3 phase to 120v single phase instead of 480v 3 phase to 120v single phase.

Excellent teacher. I did electrical years ago and is the first I understood the topic.

MY PRIMARY WINDING OF MY TRANSFORER HAVE A RESISTANCE 1.4KΩ AND VOLTAGE IS 220VAC

AMAZING VIDEO

ELI the ICE man. Outstanding instruction Dave!

Dave your a bomb teacher. You make transformer/ electrical theory very easy to digest.

I've taught electronics and have a tendancy to review quality of instruction. FYI you are excellent for new students foundational theory. watched several of your videos. If I was still teaching your vireos would be required viewung orior to my lecture.

Thanks...I really enjoying

very helpful! you are so good, please do more this kind of video please sir

Muchas gracias Señor. Gran ayuda.

Thank you! Very helpful

such an excellent explanation, well done

Just brilliant !!!

i love the way that you explain everything with your words and visuals! I graduated from electrical school but waited too long to take my JW test. Wanted to brush up on a few things before my 2nd attempt and am so glad that i found your videos! Amazing job sir!! and TY!!

Yes iwant to learn your channel good

THIS GUY IS GREAT. I just went to school about the operating theory of the buck boost transformer i am about to install on my inverter heat pump which blew up its main board that is rated on the AC supply at 208-230VAC and where my FPL power from the utility is typically 247 and has gone up to 262. Now at least i fully understand what it is doing in wiring diagram I. By the way i am working with an Acme Electric T113074. The only thing that yet troubles me is that the wire coming into the AC supply south of the AC fuse box (60A fuses) where the AC is rated at 50A max (typically 20A or even less due to 1/3HP scroll compressor motor), well the wires are 8 gauge or so, and the wires in the buck boost appear to be only 12 gauge, which say they are good for 20A and not 50A. Anybody know why the buck boost that is correctly specd out and purchased for 50A max are so thin? Also, what is the best way to connect fat low gauge wire, 8 or 10 gauge, to 12 or 14 gauge wire? Should i solder or use wire nuts? I don't necessary expect a reply to my post so in the meantime let me thnak Dave Gorodn for a great video!!!

🎉

❤

you are an amazing individual !! thank you for such a refresher

great explanation sir thanks a lot from India

Gujarati translation helping

Hope you're doing well Dave, your vids are amazing. please do more electrical content !

Great explanation! Just what I was looking for. Thank you!

Hi good morning sir This is Mardorine writing from Cameroon. My question is if the value of the inductor or that of the active reactance was not given. How then will the inductance be calculated ? Given that the angle has been provided ?

Dave, I had to watch your video several times to be sure I was hearing right. Your explanation of the secondary is good but the primary is backward. To decrease the secondary voltage, you have to add turns to the primary. Tapping the primary will raise the secondary voltage. If you tapped the primary down to the same number of turns there are in the secondary, it would be a one-to-one transformer and the output would be 120v. Your formula says it all: to decrease EsubS you have to increase NsuP.

I thoroughly appreciated your lecture, but to make it crystal clear you need to another board or more slides. Very informative and for that i appreciate you .

Great VID, thanks for taking the time.

In the delta transformer, only A to B windings are directly connected to the line voltage of 480 volts. The B to c and A to B windings are connected to the line voltage of 480 volts through a line winding in series with it.

Thank yuo Professor Dave.

This is the best explanation of feeder taps anywhere on the internet. Thank you so much for this video.

Great work from you Sir

Great explaination.....Thanks 🙏

I think this was the best explanation of this material I have ever seen.

There is no way a textbook could teach as wellas these UA-cam videos. Great job, invaluable resource toall AC theory students.

Dave, where you at? More knowledge please sir.

Very precise explanation

Wow, thanks professor Dave! That is how we learn.

out...fricking...standing demonstration and explanation

Great job explaining! you hit important points without talking about unrelated things or rambling. Also very engaging energy!

why 2.5 time for primary current??? Not understood

👍👍

You are a very fun teacher and a good one at that. Thank you Dave.

GREAT VIDEO. Just up to the 3:25 mark made so much more sense to me to explain this. I'm having neutral issues in my house so I've been told.

Excellent video, thank you so much!

Nice lecture

Thank you sir

The way you explain the theory and break down the circuit for each component is very helpful, thank you

EXCELLENT TEACHING WAY SIR
