She said she was going to build a transformer, she did. Who looks stupid here, the cute girl with the popular physics channel or the moaning karen man who named his channel after smeg.
Did you connect the secondary coil to a resistor and read the voltage across the resistor? It seems the volt meter is connected to the coil directly like ammeter. How did it read the voltage?
Thanks for the reply! And what did you use for the source? I looked like it had up to an 8 amp output. I teach at a trade school and I am wanting to have this as a lab for students.
@vt.physics Please My Friends I Need a Solution, I Have a Homemade Induction Heater, But I Have Already Used a 6mm Diameter Rubber Insulated Cable Coil with 20 Windings, Not the Enmail Cable Type, Can It Still Work?
A battery is a DC power source; transformers operate using AC power sources. The AC can be produced in a number of ways, one of which is by connecting as the load of a transistor that is being switched on and off.
The iron core that I used is sometimes called a yoke. You don’t necessarily have to clip them together…as long as the two halves are placed next to each other so that the magnetic fields of the primary coil cut through the secondary coil. Then use a voltmeter to measure the input and output voltages.
Hmm I think I've got it. Doubling the number of turns doubles the output voltage. Since it doubles the voltage, would it also half the amperage? Similarly, would it work in reverse? Where putting x Volts into the 20 turned coil would output x/2 volts in the 10 turned coil, but double the amperage? Great video, I loved the clean easy to follow editing
With a transformer, Power In = Power Out. When the output (secondary) voltage is times 5, the output amperage is divided by 5, or vice-versa as you said using 2 as the example. It all has to do with the ratio of turns on the two coils. There is an old saying, "there's no such thing as free energy"
So it doesn't really have a name, it is just a piece of wood with 2 binding posts mounted on it. Binding posts serve no other purpose than to make an electrical connection. In electronics there are probably hundreds of different types of connectors that essentially all do the same thing. I hope that helps. :)
A ferrite core is not a good choice for the typical 50 Hz and 60 Hz power line frequencies. And the cores in this video would be a poor choice for frequencies above 1KHz, where ferrites would be more appropriate.
It depends on where I consider the output voltage is. If I say that the output voltage is the right hand side where I have fewer turns of coil, then it's a step down transformer.
Ok someone help me What if we make two sperated transformers one that makes more current less voltage And one more voltage and less current And then we compuon the outplt Will we get increased voltage AND current? I am sure somthing is wrong I am new to elictronics so exuce me if the mistake was so obvious 😂
hi i have a question wont it explode when i connect primaly wireing straight to the 230ac and ill try to measure output? btw im not a native and i dont give a damn bout the correctness of splein those words, best regards
If you try to connect either side of that to the full AC mains power, you will trip the circuit breaker or blow the fuse on the AC mains. He is only using about 1 VAC in that video.
@@HashirEasa Something you can look into is how car ignition systems (coil) are working. Its DC volts input and the moment the line is cut on the secondary coil, a spike is created on the primary coil. Now with the help of a rectifier you can havè again DC volts with a higher or lower voltage output
No, on a U core or C core such as in this video, the windings can be anywhere. There are performance reasons for not placing the windings as in this video; better coupling of the windings would have had a voltage ratio much closer to the 2 to 1 turns ratio. Better coupling would be achieved by stacking the windings one on top of the other.
Not helpful. What happens when you put the power on the 20 turn side? All you measured was the 20 turn side when power was applied to the 10 turn side, and the power you put into the 10 turn side.
she is trying to show a step up transformer, if she put the supply in the 20 turn side it will be a step down, the primary coil (20 turns) will have input of 0.641 V and the 10 turns will have half of that which is like 0.320 V
What is the device on the right?? What is its output voltage?
Thanks for showing us how you print out labels?
What is the frequency of your supply
Hi, what kind of device is used on the right with the transformer sign on it? Thx :)

😂 hell yeah lol
Well you should have general knowledge on how a transformer works. It’s just a piece of iron and
Wire
Where didi you buy that iron core and that protector for that iron core can you tell me please 😊
I’ve just purchased it from an educational supplies website in the UK, such as Timstar.
Did you connect the secondary coil to a resistor and read the voltage across the resistor? It seems the volt meter is connected to the coil directly like ammeter. How did it read the voltage?
The voltmeter has a very high internal resistance, so it will measure the voltage difference across any two points it is parallel to.
Well done!! Where did you get the iron core and its clip?
It was purchased as a class kit from Better Equipped in the UK. You might also find these kits from other suppliers like Philip Harris.
Thanks for the reply! And what did you use for the source? I looked like it had up to an 8 amp output. I teach at a trade school and I am wanting to have this as a lab for students.
@@keithb.8684 It was just a 1V Westminster Power Unit. I think anything around 1 to 3V would work fine. Hope it goes well at your school!
@vt.physics Why does it work, while in the video it uses rubber insulated cables, instead of having to use enamel insulated cables to be successful?

I am using 12 volt battery...then what no of turns should be taken
Pls answer as soon as possible
Google says about 100-200 turns

@@stevebabiak6997 I used transistor and 10 ohm resistor but still reading isn't showing in multimeter
@@soumyashikha7312 - you need to have something switching the transistor on and off. An additional circuit besides what you already are doing.
Would you pls name all the apparatus you have used

What is the device used on the left?
Do you mean the yellow device? It's a multimeter to read the voltage
what gauge wire is this?
I don't remember exactly... but any wires you would just for a breadboard would do
So the wires are never connected and there insulated how does the voltage transfer yo the secondary wires?
Through electromagnetism
It's 'magic' , leave it at that
the energy transfers by the changing magnetic field of the primary coil, there is no electrical connection between the two coils
What is devices at right side??
I’ve used a multimeter to measure the voltage - you can use a voltmeter instead.
Can you mention the material and also the voltage and is it useful for step down and step up
I used some insulated wire with two iron cores. The power supply was a fixed voltage (I think it was 1V) Westminster power unit
What are the materials?
All
URGENT please, what are the name and specifications of that core
really urgent
I'm not sure what the exact specs is.... I believe it was purchased from Timstar
Do yo use only ferit core witout transistor, and whick current do you use alternate, or direct?
It's just a ferrous core (iron core) and alternating current
@@vt.physics Okey, but for low freqencies i guess , around 50 hertz?
What are those wooden box thing?
The wooden box is just to secure the wires - you can replace it with crocodile clips + leads.
Hmm I think I've got it. Doubling the number of turns doubles the output voltage. Since it doubles the voltage, would it also half the amperage? Similarly, would it work in reverse? Where putting x Volts into the 20 turned coil would output x/2 volts in the 10 turned coil, but double the amperage?

Yes, correct. The more turns, less the amperage. Turns and voltage are directly proportional. Turns and amperage are inversely proportional.
@@xydian4282 awesome, thank you so much
Search up transformer equation

@@mhikemars2971 This is exactly it - conservation of energy (or power) is the physics behind a transformer.

Nice
Is this a step up or step down transformer
It depends on where I consider the output voltage is. If I say that the output voltage is the right hand side where I have fewer turns of coil, then it's a step down transformer.
bro can we use a iron rod instead of a iron core
Yes, you can
Ok someone help me
What if we make two sperated transformers one that makes more current less voltage
And one more voltage and less current
And then we compuon the outplt
Will we get increased voltage AND current?
I am sure somthing is wrong

@Kris Pea It has to be AC because it needs a continuously changing magnetic field.
@@HashirEasa No, it have to change polarity

Are from Singapore
The core is magnetic or not
It's not a permanent magnet, but it's an iron core which is a magnetic material

I always thought they needed to be one in one side of the material and the other in the other side of the material, not in the same line.

Very very nice,is energy loss 13.2%
Poor coupling of the windings causes that. A transformer manufacturer would never build a transformer that way if they wanted better efficiency.
Not helpful. What happens when you put the power on the 20 turn side? All you measured was the 20 turn side when power was applied to the 10 turn side, and the power you put into the 10 turn side.

This music is abominable. And explanations about what you’re doing and why would have been most helpful.
