Would you give advice on 72v dc Lithium battery charger I bought from America. The transformer has overheated and the company I bought it from has washed their hands of it and refunded me. I'm trying to find out what went wrong so I can get the appropriate transformer. I live in the UK and am not having much luck.
What it is all about who told you 15A in secondary how you got that 15 from where 240V with 16 ohms load is 13.75 and where the turn ratio is used to calculate current what about if transformer rated for 1 A and you calculated 15A
We, I agree... this video doesn't consider the wire awg on the primary or secondary to determine if primary can even handle the range of current drawn! The math is okay, but leaving out a few variables to determine amps.
So I watched this video now, and now I know. So I wired up a coil, one with 6 windings and one with 3 winding to step down from 240V to 120V and boom, all fuses are out. What I'm trying to say here, no one on TH-cam can tell me how many windings a coil needs. If I want to step down from 240AC to 120AC Primary 50 secondary 25? Primary 100 secondary 50? Primary 200 secondary 100? Primary 400 secondary 200? Primary 800 secondary 400? Primary 1600 secondary 800? Primary 3200 secondary 1600? How to calculate the number of turns??
i think in most cases you’d like to have a volt per turn number of 1 or greater. so for 240v primary have 240 turns or windings. i think any number below 1 for a v/t is bad
You are explaining Ohm's law by Ohm's law. You got voltage and resistance and it took you 4 minutes to divide them. I have transformer and don't know anything but voltages and am trying to figure how to calculate power rating, but your video is obviously not going to help.
Yes my friend this man is just spreading fake information ,as in reality the power of a transformer depend upon the area of iron core used and the diameter of both primary and secondary wires used😂.
This is so much easier than doing unnecessary algebra. Thanks for explaining the simple ratios.
Thank you, my class be teaching this too fast. From single phase series/parallel to complex to polyphase in a day.
thank you for the video . your explanation is clear as water

Nice very simple method
Omg thank u. so easy to follow

Simply Fantastic Explanation - Thanks ☘️
My core 30 mm long
Dia 10 mm
Input 230
Out put 56 v5 amp
Current ac main input
Please tell me ratio
Thank you so much for your help 🙏
How to relate maximum output current with transformer coil induction (Amps in terms of Henry)?
على سبيل مثال :
لو فرضنا 930 لفة ابتدائي
48 لفة ثانوى
930 / 48 = 19.375 turns ratio
تيار ابتدائي 220 * 19.375 = 4.26 هذا تيار ثانوي هل هذا صحيح ؟
Where did the 1200v and 240v at the beginning of the video?
Thank you very good explanation...
Thank you so much.
How you decide the value of resistance 16 ohms?
Hi, I would like to understand if the Secondary Current is independent of the Primary Current?
No. The primary current is dependent on the secondary current.
What it is all about who told you 15A in secondary how you got that 15 from where 240V with 16 ohms load is 13.75 and where the turn ratio is used to calculate current what about if transformer rated for 1 A and you calculated 15A

ty
how do you do amps to mA?..Thank you
1A = 1000mA
Thanks

If I want to step down from 240AC to 120AC
Primary 50 secondary 25?
Primary 100 secondary 50?
Primary 200 secondary 100?
Primary 400 secondary 200?
Primary 800 secondary 400?
Primary 1600 secondary 800?

How to calculate the number of turns??

How did you get 16 ohms
made it up
If don't no R then

just multiple the volts by amps equal power
@@mtevans6196 Amps of what? There's no current without circuit. And in circuit it depends on load.
