You are an amazing teacher!!! The information you share here is very clear and the combination of the perfect tempo of your speech makes everything very easy to process and understand for non engineers guys like me. On the production side: the editing, lightning and mic position are great too!! , real professional video. Keep doing videos like this. Best regards
Impressive video, the knowledge i had but, i always appreciate experimental demonstration of electromagnetic concepts (as opposed to trowing a bunch of laws and theories at the viewers).
Excellent. Actually seeing the efficiency improvement by introducing a simple iron bar (starting at 2:42) in an actual physical transformer setup is very memorable - versus, say, a computer animation. That current meter jumped so hard it whacked the casing!
Great info and well presented, Is there a DC transformer that will step up current so i can melt a single wire strand? I was planning on trying to use a dunamo generator to power said transformer.
how much current produced how much gauss? how much tesla or gauss power required to produce one ampere of current for one hour how we increased the voltage from battery cell to light a 1000 watt bulb for one hour so the relationship between all above equation thermodynamically correlated to each other?
While Faraday was a great scientist too, the Danish Hans Christian Ørsted discovered electromagnetism before Faraday came up with induction. This was the basis for everything Faray wrote down.
Awesome video, but I disagree with the statement at 8:02. The Faraday's law says EMF=-N*dФ/dt (d ~ delta). The flux (Ф) is in the core and is the same for both coils. Twice as many turns will have twice the voltage because N is twice as big compared to the other side, but flux is the same in both (same concept as a series-connected circuit: a resistor of (2R) Ohms will have twice the voltage across it than resistor (R) Ohms because its resistance is twice as high, while the current is the same).
Great explanation. FYI, the impedance equation went by too fast for me. Overall, slowing down the presentation would help me follow it better. Still, a really good explanation and demo.
My question is thought where are the electrons in the secondary loop coming from for the current? As in,sure the magnetic field induces an EMF but where does the current come from that takes advantage of the voltage difference and goes to ground?
Nobody can say your name and nobody can answer your question... Save me... To really understand electrical stuff you have to acknowledge AND accept one critical aspect that isn't talked about very much- you'll find this in every branch if you dig deep enough- At it's core, beneath all the carnival a days laws and magneutella spreads, the basic fundamental explanation for potential differences between electorals, electron notes neutral post igniton switches whatever you pick- AC is for Alice Cooper, DC is Dark Craft and it's all made functional through Black Magic.I mean, just looked at trans sister.., it's MFN black magic...
Thank you very much for the video. The thing I do not get yet is to why Transformers are impedance matching devices. At 4:41: Why is the first light bulb not lighting up anymore: "There is an increase to the impedance in the current flow". So is it like this: There is still voltage across the first lightbulb, but not so much that the lightbulb will turn on? I guess what confuses me is that if i think away the second lightbulb it seems to me that there is only a closed circuit with a lightbulb (if anyone can explain I would be very happy, with mathematics is also fine if it is easier). Help is much appreciated:)
..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
is it possible to rig/create a system so to lower electric bill by using transformers or some other device?? so to be able to get away with a low input at be able to power a bunch of stuff ??... say if you use a pc all day your common bill may be 40 dollars per month but with the rig your bill goes down to 20 dollars?
Robert Ostman Umm, no. The power is still the same. Volts x Amps = Watts. If you have a 120v outlet on a 15 amp breaker, you'll only be able to get 1800 Watts. So if you convert it to 240V you'll only get 5 amps. You COULD use a 10:1 transformer to convert that to 12V, and then use a few large diodes to convert the current from AC to DC. They're are a bunch of RV appliances that run on car batteries (12V DC) that are much cheaper than regular household appliances, THEY might use less power to function, but they'll also be less powerful. As long as transformers generate heat, and they do, you won't be able to get out more than you put in.
Input voltage/Output Voltage = Turns1:Turns2 Simply measuring the input and output voltage gives you the answer to the turn ratio without ANY further math. If you have 1v on the input and 2v on the output, then the turn ratio is 1:2. There is double the number of turns on the output side. If you have 1v on the input and 0.5v on the output, then the turn ratio is 1:0.5, or 2:1. There is half the number of turns on the output side. Not exactly 'challenging' for students, but I guess it would make you immediately aware of those who don't understand. More challenging would be to ask them to give you the exact number of turns(roughly) as opposed to just the ratio. It would require testing the resistance and measuring the diameter of the copper wire, but would also be doable without disassembling the transformer. Just some calipers and some simple math is all that is required.
Now I know why my teeing transformer not reading any volt. Because there is no output light bulb on the secondary coil. Circuit is open. Just a volt meter will read o
Sir could you give me the link of the website from where you bought those colorful coils and that core. It will be really helpful to because I am a IB student and want to research upon transformers and to build one I need these things. I could have made this by myself by arranging the core and by binding the wires but due to corona I am not allowed to go out. So, plz I request you to give me the link of the website from where bought those things. I hope you see it and reply to it as soon as possible.
Good video very educational I do my own bits fly make drons use to fix laptop consoles cars so on and know risistors couler code in head no hard to remember but never got to know what impedance meant thanks do now
excellent, I have a micro hydro generator that outputs a max of 80vdc 220mah, I'm trying to increase the amps even if I have to compromise volts, do you have any advice for my experiment I would greatly appreciate it.
I'm assuming the generator is producing ac current as that is important. Otherwise, the voltage rating of the transformer isn't too much of a concern as long as you're not using a very small transformer. As long as the primary wires are around 18-16 guage you should be fine. The frequency of the ac in might be a concern. If the input power is too low of frequency the transformer might get hot. You may just have to experiment.
No step up transformers are more efficient for transmission of power, but this is not free power. When you step up the voltage, you step down the current at the same factor, so the power stays the same less any losses. Lower current creates LESS i^2R heat losses on the lines. The heat of the transformer itself has to do with the power flowing through the transformer and its associated characteristics such as cooling method, insulation, and core losses.
in my years of being an electical engineering student, this is probably the best explanation I have heard and seen till now. Thanks.
This video is brilliant, all the simple physical demonstrations perfectly convey the concepts you discuss.
this is great - i really wasn't expecting more than a 'dummy' video but actually somewhat original and thought provoking too!
Where have you been all my life, this is perfect education.
what a surprise. I never saw the 2 bulb demo. what a suprise, to still be learning about transformers. thank you

Very nice. Easy to understand.
Good video, for other viewers benefit it would be nice if you went more into flux path, leakage, and transformer impedance.
Great ideas sir
Your video's ottro music reminds me of the past... :( So many people I knew were still alive...
Great demo!
What will happen if we have no load on the secondary but connect it as short circuit?
Wow very nice ❤
Great .Thanks a lot
Plus i did not expect the 1st winding bulb to go when undoing the second still scratching my head like some majic trick lol
Superb.
good job!!!

I don’t get the impedance part.
excellent, I have a micro hydro generator that outputs a max of 80vdc 220mah, I'm trying to increase the amps even if I have to compromise volts, do you have any advice for my experiment I would greatly appreciate it.
erick sal You could build a transformer with twice as many primary windings as secondary. It will half the voltage and double the current
John Lacy should I start with any voltage transformer , I mean rating? what minimum voltage rating should I start with?
I'm assuming the generator is producing ac current as that is important. Otherwise, the voltage rating of the transformer isn't too much of a concern as long as you're not using a very small transformer. As long as the primary wires are around 18-16 guage you should be fine. The frequency of the ac in might be a concern. If the input power is too low of frequency the transformer might get hot. You may just have to experiment.
the gen produces dc
erick sal Transformers need ac input to work. There is likely a rectifier in your generator, if you bypass it you will get ac output.
Where can i buy this transformer kit for demonstration?
I would like to know as well!
@@mr.leighsclassroom6628 Me too! I have been hunting high and low with no success!
I know it can’t be, but if you step up aren’t u getting free power.?
No, not according to Ohm's law, you actually lose more power via heat, touch a transformer around your house, its rather warm or even hot at time.
No step up transformers are more efficient for transmission of power, but this is not free power. When you step up the voltage, you step down the current at the same factor, so the power stays the same less any losses. Lower current creates LESS i^2R heat losses on the lines. The heat of the transformer itself has to do with the power flowing through the transformer and its associated characteristics such as cooling method, insulation, and core losses.

These videos are awesome but it's a lot to shove in an 8+ min video.. All these concepts could take a 'semester'/ what have you to go through
