I really like this video because it's clear concise and to the point. No nonsense, no fluff, and for that, you get a thumbs up from me. Well done!

good, slow, methodical teaching. easy to understand. thanks very much

Thanks for the video. The explanation and illustration is very clear and concise.

Excellent presentation, and well done! Thank you!

I like your tutorial video and all your feedback comments.easy to understand.its really helpfull for me and many people.keep it up and thanks a lot sir.

THANK YOU! Finally, transformers explained in a straight forward manner!

Good Information for non-professional people like me...

Very well explained. Thanks, well done

Thank you for sharing Well explained & professional

u are great sir.like your tutorial.its easy to understand.

Thank you. Very nicely explained. You are a good man!

thanks a bunch for the video and explanation, you are awesome!!!!!

Thanks for such a great video. you are doing really good. keep uploading:-)

Thank you very much. Greatly explained.

Very interesting and easy to follow, thank you. 2016

Thanks for the good info! I'm building a project desoldering iron and Hopefully this is a good step in the right direction.

Excellent video and well explained. Thank you

very good information .. I learned a lot

Very informative, I have some unmarked transformer I need to measure and label for future use. Thank you!

very useful ! thanks john

Thank you for sharing Sir, very clear!

I LIKE YOUR STYLE, "We have the option of doing this two ways, the right way and the WRONG way.

Thanks John, Never to old to learn. I now know a bit more in this regard.

great video

Thank you, the turns ratio formula at about minute 2.40 will help me determine the size fuse I need for a (120V to) 14 volt 1.1 amp transformer for a little lamp I am trying to fix.

I woud do measurement all wire of transformer againt case of transformer...isulation... Best video i see this about topic...thank you very much...

very well done.

Well done.

I have several transformers that I have picked up over the years.Most are from microwave ovens but a few are smaller or larger and the sources are long forgotten. The other night I decided to test them to see what the output voltages are and even though they may say 120v and 60hz when I plug them in using an old cord and an outlet on my work bench, they pop my work bench breaker! They may have anywhere from 2-6 wires coming off the secondary, none touching, and only 2 wires on the primary, but when I plug it in POP ! Any ideas? Thx

good info.

clear and consice thank you .. how should you determine fuse size ty joe

Just wondering what size fuse you should use to protect the Transformer

i bought a Weller soldering station from Amazon that uses a 110v input but i live in UAE where the mains power supply is 230v, any idea how to work it without damaging it..!! jazakom Allah

if the trans is rated for 2amps the fuse also needs to be 2amps? i think i used a 4amp fuse instead, also it says 12 volt 2amp for the outer wires but there is a yellow/green wire in between them ,would that be for 6v and 4 amps instead? it basically says " grn-grn/yel-grn:12vct 2a" does this mean any connection will give 12 volts or is this still a center tap wire?

On the Hammond 25 volt, I want the full 25v so what so I do with the Green/Yellow striped wire... just cut it off ? Thanks

..but what would happen if i reverse the input to output..or power through the secondary..would it be a step up...is it ok to do that...fused on the input.. of course

goes to show i learn something new every day.thank you very much .)0 ohms = a short in the transformer.That i did not realize.

good and perfect

Very good

is bad that if the resistances between the CT to a secondary coil and between one secondary coil to another is the same? your readings from a secondary coil to CT is aprox half that of one secondary coil to another.

Was the secondary winding's resistance lower due to wire gauge, or due to shorter total length of conductor in that winding?

Hello, thank you very much for your video, it was very helpfull ! Where can I get such multimeter probes ? They seem handy with their retractable "hook".

Gud

I have a transformer in my air handler with 240v input but has a 31,15v output under load. It’s supposed to be 24v. Would this or could this cause my 5a fuse to blow? It’s basically 7.15v too high.

Where can someone either salvage them selves or buy a stepdown transformer to go from 120 volts down to anything between 12.5- 14 volts

1929fordhotrod+ What size fuse should we use for this setup so we can gauge on up and down?

thanks but still got questions unanswered. when you connect the primary to power arent you causing a short circuit? 110v/15 ohm= about 8A of current flow whichis veryhigh. what am I missing here?

Very well explained sir. Transformer in my speaker got burnt may be due to high voltage. Replaced it with the help of your video and attached a fuse as well to it. Thank you. I have a query. The transformer input voltage is 230V (India) and output is 12V-0V-12V / 1 Amp. What should be reading for fuse.? As of now, the fuse which I have inserted has 3A/250V written on it. Any suggestions.? I may keep the speakers till you recommend me the fuse.

But wouldn’t the fuse protect your ❤️ from taking too much amperage acrosst it? And btw, you have many plastic power apparatus with bolt in transformers where your at? Can’t say I ever saw one here..... 😆. I enjoyed your video! Just heckling.. 👍🏼&subbed

good.

hi if a read open on primary wires do I have a bad transformer I'm not getting any reading on ohm setting I do get 1.5 ohms on secondary wires

sir how can we determine the rating of transformer or output current of it

I have read that by step-down transformers the voltage goes down and the current goes up. Why is by these transformers the current so small (0,2 A; 0,5 A)? What are they used for? What does depend on, whether the maximal current is 0,2 A or 2 A? On the size of the transformer? More wire on both sides for more amps? Thanks for the interesting video.

Thanx

*Did you know?* Tape can be hazardous to hold down cords! 1: If a fault occurred and it heated up the copper/metal/iron wire or the plastic coating of the wire, it can melt the tape because of its paper material, however, it does not light on fire and turn in to ash. 2: This might sound funny and it is a hose-like situation. Tape has a great performance holding down it’s target. Just like a hose, it can cause a voltage clog. To test, you will need 2 ---.---- digit voltage readers on the left of the center and the right of the center, wire (not bare, or without plastic coating it), and tape. Tape the center area of the wire like it is at 9:56. Then, hold 2 readers on each side of the center. I had 0.06 volts travelling through the wire. Again, like a hose, the tape acts like a foot on a hose, so it clogs a little of the voltage. Start: Left: 0.06kV; Right: 0.04kV (See?). A bit in: Left: 0.11kV, Right: 0.00kV. Do the experiment yourself, but I used a bit tinier wire to test it.

How can I step up 0.3 V to 1 v AC voltage? using transformer

if my input voltage change will my output voltage change at 12v transformer

what would each of the secondary winding leads read if put to ground?

i have purchased 12-0-12 3 amp transformer when i check this give output me 6 amp. i have 100 watt audio board which required 12-0-12 3 amp pl hekp

What is the cy? You said it was 60 cys but what is cycles in a transformer? thanks.

Lol correct way or incorrect way! I hope that eas a shot @ anyone who dislikes your vids!

How to test a step down transformers maximum output current?

sir are you there to reply to some questions?

First transformer is 12 volt, and the fourth (big) transformer is 24 volt. so the first transformer's size is almost half than the fourth 2 amp 24 volt transformer.

what is the fuse rating used sir?

if viewer has the electrical gadgets you mentoin . HIGHLY UNLIKELY they would need this video.

Well,OFFSHORE mean Chines ? am i right, sir?????????

Forget AC. Please explain DC to DC trnsformers.

i think for safety ppl will plan on removing the power before they remove the fuse anyways

excuse me sir i have a transformer (step-down) from 220v to 12 volt its output rating is 12v 2 amps i have 3 output wires 12v-GND-12v can i get a 24v from this transformer by any means?

can you explain what your talking about were not all experts
