Building a Transformer - Physics Experiment

You can build a step-up or step-down transformer using some insulated wire and two iron cores. Test it out using a multimeter afterwards.

What is the device on the right?? What is its output voltage?

[keithb.]

Well done!! Where did you get the iron core and its clip?

[hugofolpp]

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

Thanks for showing us how you print out labels?

[BeezyMusic]

Another question. Sorry for two comments. Does it matter if the wire is coated and if not is it okay if it’s touching or does it need to be like a neatly wrapped coil.

I am using 12 volt battery...then what no of turns should be taken

[SethKnuth]

Hello, Is there any chance that you have a schematic for the Westminster power supply?

[gpmonaco-em]

It looks like the wiring has been connected to the DC (red black) outputs of the power supply and not the AC (yellow)? A transformer needs AC to work?

[kevindewinter]

Hi, what kind of device is used on the right with the transformer sign on it? Thx :)

[dendemoelias]

Is this a step up or step down transformer

[redhytech]

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.

[samarthchugh]

Would you pls name all the apparatus you have used

[conqueror-ispi]

URGENT please, what are the name and specifications of that core
really urgent

[suhyunshawnkim]

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?

[madhuu]

Where didi you buy that iron core and that protector for that iron core can you tell me please 😊

[marktony]

So the wires are never connected and there insulated how does the voltage transfer yo the secondary wires?

[bulla]

the metre is not in the correct range between AC or DC it looks in the 20 volts AC rage or is in DC mA rage how do you gets 120volts AC or DC

[malaika]

hi! what is the name of the wooden apparatus that you are using to join the wires?

[aatrox]

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

[bharathv_]

bro can we use a iron rod instead of a iron core
