What is the behavior of subatomic particles when there is a voltage but no current? I fully understand that if there is no load there will be no current since there is no path for the circuit to close. When we use a phase tester and insert it into the phase receptacle of the electrical outlet, it turns on showing that there is electric potential at that specific point. What do you think that happens with the electrons? are the charges inside the atom polarized or charged with potential energy waiting for a path to flow? I hope you can get my point.
If we apply an AC voltage with no load, there is no current in the secondary winding, but there will still be a small current flowing through the primary winding. This small AC current creates the magnetic field in the core, which then creates the AC voltage on the secondary winding. The issue is that the mathematical model for an ideal transformer does not describe what a real transformer is doing.
@@EugeneKhutoryansky Thank you for your answer. However I undestand that part you just explained to me. I would appreciate so much if you could please answer this question I will ask you, so far nobody knows the answer. What is the behavior of subatomic particles when there is a voltage but no current? I fully understand that if there is no load there will be no current since there is no path for the circuit to close. When we use a phase tester and insert it into the phase receptacle of the electrical outlet, it turns on showing that there is electric potential at that specific point. What do you think that happens with the electrons? are the particles inside the atom polarized or charged with potential energy waiting for a path to flow? I am taking about electric potencial at one point. I hope you can get my point.
Even if there is "no load", the two wires with an open circuit will act like a capacitor with a very small capacitance. Therefore, this capacitance will keep charging and discharging. So there actually is a very tiny current flowing to charge and discharge this capacitance. And when the capacitance is charged, one of the wires will have slightly more electrons and the other wire will have slightly less electrons.
I am an inventor who will become a blip in the many millionaires of this world. I failed to understand electricity (and physics) up until I was 26. Your videos have contributed in a priceless & profound way in my understanding of everything physics, and you are largely to thank for the success I will see in my endeavors now that I understand physics, particularly electricity. Your part will also play a role in me understanding electricity so well so as to prevent fatal shocks. I can't find the words to thank you, so when I am where I predict I will be within the next few years, I will seek to pay you back somehow. For now, I will subscribe. Thank you for everything you do for our community, and humanity.
I've been following you for a while now, but I literally just switched my major to Electrical Engineering. and the moment I did, you're pouring out gold on your channel.
Eugene thanks so much for this free very highly effective videos, God bless you my friend. and am sure you know this but the best think than you have done to help people understand this concepts is the visualization animation. thanks again.
Wow!!!! The animation and explanations you gave 5 years ago are the best till date. Its easy to understand through visualization and your technique is best and unique. Hats off to you, keep uploading more precious content. RESPECT +++++++++++
Amazing how it shows the analogy of transformers to gears as well. It looks just like the current on both sides is connected like rotating shafts are connected by a chain drive or timing belt. You can see that there is a ratio of current, analogous to a ratio of rotation rates in gears. It would look like rotating gears, if he reversed the handedness of the secondary coil, to the current rotates in opposite directions.
I really love your videos. I've linked them to people who want to understand electricity better. I've also gained knowlage and understanding from them. Thanks for making them!
Amazing! I could never wrap my head around why one side of a transformer can have a higher voltage but less current than the other side. However, your visual explanation has completely answered my question and exceeded my expectations! Thank you very much. :)
2:14 let's pause the video here and apreciate the use optical ilusion to make the right voltage arrow (green one) smaller or bigger depending on the output voltage. clever Eugene is clever.
i wish all engineering lecturers would sound like you..knowing the right thing to teach n in the best suitable way thats easy to grasp even by a laymen..thank u soo much..we need more n more videos..all the best
really excellent videos ... Brilliant! :-) And i loved the backgroung music on this video too. (please post a note, perhaps for future videos, noting which background music was used) :-)
i saw a lot of videos in you tube but your videos r some thing diffrent u r the best man doing electric videos thank u so much i hope u can explain all the electric science like this way
If the windings both share the same axis around the core, and are wound with the same handedness, the waveform will be the same. Use opposite handedness in the same location, and the waveform will be inverted. If by contrast, the windings are on opposite sides of a rectangular closed loop core like they are in this annimation, then opposite handedness of coils means same waveform while same handedness of coils means opposite waveform. This example shows opposite sides of a rectangular closed loop core, and opposite handedness of coils.
@@EugeneKhutoryansky Why then some people say that until you do not plug a equipment into the outlet you wont have any current flowing. ? I can see in the video that for the magnetic field to exist it is necesary to have a current passing through the wire, and for there to be voltage current needs to flow, hence how come can u meassure voltage at home between hot wire and a neutral if it si not supposed to have a current ? I am confused
Man you are doing a very good job, im also writing some tutorials about engineering and i loved your idea to use 3d animation to illustrate and facilitate learning again congrats
it's been five to six years since I found this channel on the web at that time this was new stuff I knew in the future this gonna go like Kaboom in the youtube algorithm.
