I was about to run away from this video half way through. So many educational vids like this go from simple elementary explanations to quantum physics equations in a matter of seconds. But this video was a steady incline of new information that even I could grasp after a few drinks. Thank you so much for this!
Thanks. It didn't happen often but every now and then I had the time to do a video with a thorough explanation like this. Another is one about how a crystal radio works th-cam.com/video/0-PParSmwtE/w-d-xo.html Thanks for watching!
Dear Steve, I just wanted to take a moment to express my sincere appreciation and gratitude for the incredible educational content that you create on your channel. As someone who has always been fascinated by the world of physics and technology, your videos have been an invaluable resource for me in expanding my knowledge and understanding of these subjects. Your ability to break down complex concepts and explain them in a clear and concise manner is truly remarkable, and your passion for these topics shines through in every video you create. I am constantly amazed by the depth and breadth of your knowledge, and I have no doubt that your work has helped countless others, like myself, to deepen their appreciation for the wonders of the universe. Thank you for all that you do, and for your unwavering commitment to educating and inspiring others. Your contributions to the world of science and technology are truly immeasurable, and I feel fortunate to be able to learn from you on a regular basis. With sincere thanks and admiration, Caio Cesar.
Thank you very much for this video! Im from Brazil, and work in Musem of Arts and Trades, in Belo Horizonte. Here have a Wimshurts machine and i needed to understand better how works, and this video helped me so much! I really love it! Perfect explanation, i am sending for all my collegues, thanks!!
Thankyou very much for that informative video on the basic construction of a wimshurst machine. I am an electronic engineer and have always been fascinated by this device ever since childhood when I used to see those old 1950s Frankenstein movies where they had huge ones made to show massive sparks which probably couldn't have been achieved and also jacobs ladder sparks which would have been unfeasable using them. But in all those years even though I understood the principle behind how the charge was accumulated, I never took the time to discover how they actually were constructed. I'm retired now and plan to make a big one with the best insulators I can find and see what I can do with it...
Going into this video: "Hey, no fair. You've already explained how a Wimshurst machine works" Watching this video: "Oh. Wait. Nevermind. This one is GORGEOUS." Beautiful job. Good editing, incredible animation, loved it.
I am so greatful for this great video with the perfect balance of explanation and observable reactions happening. Thank you I have only been able to get this with this video
I got my first Wimshurst machine (and a Morris & Lee VDG) from Edmund Scientific about 50+ years ago. I've have many books and seen this explanation many times, however your presentation is by far the best I've encountered. Thanks.
Thanks. When I made it, I set out to make another video which I could be as proud of as my How a Crystal Radio Works video th-cam.com/video/0-PParSmwtE/w-d-xo.html They take a lot of work but are worth it.
Wow!!!! Amazing demonstration, thank you (thank you!) so much for taking the time to do all this! It's so much fun I am so excited to one day build one of these to experiment and play around with they are so cool!
Hey Amigo nice to see this video again...the Wimshurst video you made last time was one of the best !! I even tickled you to make an '' N machine '' after that i remember!
That's strange. You're the second person to say they've seen another Wimshurst machine explanation by me but this is the first time making one that I can recall. I made a start a few years ago but didn't get past the intro. As you can imagine, it was a monumental amount of work. I also wrote a Hackaday article but that's all.
Brilliant explanation - much superior to others I have found on the internet. Ever since I first saw a Wimshurst machine at school, 50 odd years ago, I have been mystified by how it could possibly work. Now I know (I think). Thanks!
Ditto! 45 years ago there was one stored in the back of our Science/Physics classroom. I never knew the name or what it was for - thanks for teaching us!
Wow! I've come across your videos from time to time and after I saw the one you made about the tea laser a few years ago I checked out most of what you had posted. You never used to really attempt to explain things in this sort of depth and always sort of underplayed your understanding of things. I have to say that your explaining in this video is not only just as good as I expected, but the animations are perfectly synchronized with the script and very clear and well done in their own right. Did you do all the CGI yourself too? In any case I'm very happy to see your channel continuing to mature beyond what was already a fascinating catalog of fun projects and demos. I'm sure the algorithm fairy will bring you at least another 100k subs by 2020 if you keep this up.
Thanks! I'm glad you like it. I've done a few of these long, detailed explanation videos but I haven't done a lot because, as you can guess, they're a lot of work - 3 weeks fulltime for a single one. But I do enjoy doing them. Another one which I did a long time ago and which you might also enjoy is my How a Crystal Radio Works video th-cam.com/video/0-PParSmwtE/w-d-xo.html And yes, I do all the CGI too using Blender, a free 3D modelling and animation software.
In the 1950s my father had one of these which he was storing in the loft until he thought I was old enough to appreciate it. Unfortuneately it got broken in a house move when I was 10 so I never saw it work or understood what it was all about - very glad to find out 65 years later. PS he also had a Telsa coil which survived and gave me a lot of experimental pleasure
wow really good explanation! I've always wondered how that worked. I've heard in the invention of X rays, the Wimshurst was used to generate high voltage for the first X-ray tube - still somewhat in its experimental stage
Thanks! It took a long time before I came up with how to explain it well, but I really wanted to do another "work of art" like I did with my crystal radio explanation th-cam.com/video/0-PParSmwtE/w-d-xo.html.

fantastic explanation mate. For all those who don't get it ... its all about shed tech, when high tech was something you could build in your shed! Today high tech is microchips and programming ... difficult to build in my shed!
Hello again Mr. RimstarOrg ! , Sir, I think I sort of solved the sector scraping problem. My Wimshurst Machine used four metal spikes to collect the charges. Two for one side and two for the other side. I just took a pair of pliers and removed them and replaced them with some aluminum tape shaped like a flat point that brushes up against the disks BUT wouldn't dig into them like the spikes did. Sir, after solving another problem I had I have to say that I have waaaaay better ESD than before. Its like the day I first got the machine. Good as new ! Okay, now I'm going to see if I can make a Wimshurst Machine FROM SCRATCH! The one thing this improvement to my Wimshurst Machine has taught me is that I should NEVER be afraid to experiment scientifically with Ideas and things ! If I can make a Wimshurst from scratch then I can make multiple units and drive them all with one dc motor and interconnect them with gears. At that point, "Skys' the limit" because I will be able to generate any amount of high voltage. I thank you sir for your videos, they're really helpful in mullng thins over in my mind. I hope I can talk like this with you from time to time, thank you again.
I thought this was great. Thanks so much for the video. Trying to get an old one working that was found disused in a back room at our school, dreadfully corroded by acid fumes and its leather belts were rotten. Further, it looks as though someone was modifying it back in the 70's and didnt complete the job. An interesting rebuild.
Great video, excellent explanation. But you have forgotten to clarify an important point: How does the tension in the Leyden jars continue to increase? After all, the electrons in the increasingly negatively charged jar must repel the electrons from the collector at some point, unless the tension at the collector keeps increasing to overcome this hurdle (and vice versa for the positive charges). The explanation for this phenomenon is hidden in the capacitor formula's: The two opposite sectors (one positively charged and the other negatively charged, in your video the ones at twelve o'clock ) together form a capacitor with a certain charge. The well known capacitor formulas are: C = εA/d and C=Q/V. Rewritten: Q/V=εA/d. (The capacity C, Farads drops out of the equation) The permittivity (ε), the surface area (A) and charge (Q) do not change (no leak assumed). Now that those two sectors at twelve o'clock are rotating away from each other, the mutual distance (d) does increase sharply. As a result, the (negative) voltage (V) across this capacitor must increase accordingly, and is always higher (lower) than the voltage across the Leyden jar. In theory, if there were no discharge at all (which is impossible) , the tension between the two jars could rise to infinity. I built a Wimshurst machine myself a few years ago. Maybe I will make a nice video with a detailed explanation concerning the build and theory. In the mean time you can see it sparking here: th-cam.com/video/QrFva1FmDhk/w-d-xo.html
nice video it helped me to understand the aparatus, thank you very much! but one thing is missing a bit. the charge at the opposite sectors must become continuosly higher because otherwise it would not accumulate in the leyden jars. the fact that at the beginning it have only ONE sector charged and it influences charge separation at TWO sectors on the other plate makes the over all electric field stronger. this two charged sectors then rotate further and influence even stronger charge separation on the other side sectors and so on. so the charge separation effect adds up every time the "new/higher " charge meets the opposite neutralizer, and therefore charge becomes alternately higher on the front side and back side and cycles clockwise and anticlockwise.
That's correct. The charge on the sectors builds but quite a bit. The limiting factor is the leakiness of the sectors. In the dark, they glow with corona at their sharp edges and with corona between them. You can also smell ozone. If you don't collect at least some of the charge at the collectors then it becomes hard to turn the crank due to the strong attraction between the opposite sectors which in turn is due to the amount of charge on them.
I must be slow. I don't understand how this generates a charge and why it keeps growing. All I see in the description is a lot of capacitors and wires holding charges. If you put a charge on a capacitor and then start connecting it to other capacitors the charges move and distribute but they don't grow in magnatude. They just keep getting smaller as you spread the charge over more capacitors. I can grasp how this acts as a charge "sorter" so random starting charges get sorted by the action of the neutralizer bars moving charges. But I don't get how those sorted charges can ever exceed the total starting charge. So what is the mechanism that causes the the charge to grow larger in this device? I understand the mechanical motion of the device is the source of the energy generating the charge but I don't grasp how this works. And why are the collector's pointed air gaps? Why not use another wire and brush to collect the charge? And what keeps the charge in the liden jars from returning to the disk? I don't understand why there is a one-way flow at work there.
My friend is convinced that this device can be used as a source of free energy. "I can harness this, regulate it, and then store it so it can later be used to chrage my batteries!" Im not sure how to explain how that is not exactly likely. He feels he just has to start it and walk away. Then come back to full batteries. That isnt true is it?@@CurtWelch
Hi RimstarOrg; I have to comment a bit about where the energy is obtained to cause the separation of the charges and generate such high voltages. The separation doesn't come about for free! Work must be done to do the separation. The plates on the disks form capacitors, "variable capacitors". 1. The plate pairs when initially charged have relatively high capacitance between each other. The energy in this capacitor is E=(CV^2)/2. 2. The capacitance of this capacitor is inversely proportional to the distance between the plates. 3. As the disks rotate the capacitance deceases between the plates. Since the charge in this capacitor is constant the voltage increases the further they are separated. It takes mechanical work to oppose the attractive force between the plates. This work converts relatively low initial voltages to substantially higher voltages. Note! Power is Voltage * current, W=V*A. The initial plate charging current is the same as the current being collected and delivered to the Leyden jar. But, since the voltage is much higher the delivered output power is much higher then the initial input power. The added power is caused by the mechanical work expended in turning the disks. redrok@redrok,com
I made this video explaining how to make one using as simple parts as possible th-cam.com/video/puC6-UaT9Fk/w-d-xo.html. It's not powerful enough for a lot of the demonstrations shown in this video but it works. I plan on showing how to make one that is powerful enough though.
Nice presentation. Let me understand the operation enough to ask questions. Why the capacitors continues to take charge and not saturate? or will the charge in capacitor flood back into the next charge carrier?
Brilliant! I never knew they where as complex as that - the ones I played with as a boy in London's Science Museum are all mahogany and brass with most of the workings hidden away. So the one on your bike - could you put a xenon strobe tube across the spark gap and have a headlight that made it look like everything was static? (pun intended)
The Leyden jars are for getting bigger sparks. They collect additional charge so that when the spark gap breaks down, the spark will have more charge (current) and so will be bigger and brighter.
How much power does it generate. Enough for a AAA battery, or for a cell phone, or can a 12 volt battery be charged 🤔 If for a 12 volt battery 🔋, how long to change it up from 7 volts to 12.5 ...??? Excellent video. Ty so very much. Good voice and gate in speech. I have a little bit of electronics knowledge but more basic and a tiny bit more in a few areas . I took electronics in high school and been around a few guys who know it really good. But I just have not retained it over the years. Old part now and slower these days. I love energy and renewable energy, especially. I did know a man many years ago that was Nick Teslas lab aid and associate who showed me things beyond belief, but he demonstrated them. He had a few photos of him and Tesla and some papers they worked on. He was real. The man was a little over 100 at the time I met him. He really liked me. I liked him a lot as well. He passed on at 112 years of age. That was over 20 years ago. He was a church decon since about 1942, I believe his church certificate said. So again ty so very much for sharing this knowledge ❤️ with us.
It's not really intended as a power generator. I takes the mechanical energy of turning the crank and turns it into electrical energy with an efficiency of only a few percent.
@@RimstarOrg it was designed to create high voltages but power requires amperage also and it has very little of that as in Micro amps. I recently used it to power the tesla hairpin circuit or stout bar experiment with some wonderful results. But that being said i have not tried to hook a step down transformer to it to increase the amperage pulse when the gap fires..
very good explanation and animation! just a small detail, you showed four negative charges flowing from a negative charged sector to a neutral charged one, but if it was like this, what would stop the negative charges to flow back where they was before? after all, it would be like at the beginning. I think the neutralizer instead works by equalizing charges between sectors, exactly like two caps in parallel reach almost the same voltage, so in your animation only two of the charges should move.
The charged sector that's on the other disk is what stops the negative charges from flowing back where they were before. When the disk rotates a little more and the sectors are no longer being touched by the neutralizer then there's no path for the negative charges to flow back along. And the repulsion by the negative sector on the other disk is still on the other side long enough for the disk to rotate away from the neutralizer. I first thought that four charges should move and then realized that it would be just two, like you said. That's when I was thinking like you, that the neutralizer was equalizing charge. But then when the destination sector was next rotated to where there was a neutralizer on the other disk, then it would have only the strength of two charges to repel with. So on the other disk, only one charge would move along that neutralizer to another sector, and so on, with the amount of charge moving around being less and less all the time. So I thought that can't be right. That's when I realized that the two sectors and the neutralizer are all electrically connected and the explanation I gave made sense.
Very nice explanation and animations indeed! For me the question is not so much why the charge does not flow back, but why it is completely flowing to the other sector in the first place. I would think that it would almost even out between the two sectors. Can you explain why it would flow entirely to the opposite sector?
Thank you for great explanation and visualizations. There are 2 Questionable statements in video. These are my clarifications: Capacitor stores charge in dielectric, not metal plates. metal only used to shape a charge and conduct it. Also charge never goes inside metal. Due to repellent effect it only can travel on metal surface. 2. Are electrons and protons real? it is just a model. In the ancient physics only positive charge particle exists. Negative charge is a luck of positive particles.
"Capacitor stores charge in dielectric" No, you can build capacitors without any dielectric material. "charge never goes inside metal." Oh yes! It is inside all metals. Conduction electrons are everywhere in a metal. You are probably confusing direct current with alternate current, where there is a so called skin-effect. Are electrons and protons real? it is just a model. Agreed, but what's the point with respect to what is said in this video?
I understand how this works, but nobody seems to mention the voltage multiplication effect of the contra-rotating discs. At school we were taught that Q=CV. When two plates are opposite, they have a fixed charge; as they move apart, the charge remains the same, but the capacitance is reduced, causing the voltage to increase proportionately. Once the plates are at maximum distance, the voltage increase is sufficient to enable the charge to 'bleed-off' to the leyden jars via the corona between the plates and the collector points. Have I misunderstood something here or just missed a point?
Hmmm... Interesting. I was aware of the voltage increasing as capacitor plates are separated but hadn't considered any part it may play in a Wimshurst machine. That voltage is between the plates but I guess since the collectors are capacitively coupled through the collectors then the voltage on that side would be affected too.
That's hard to answer. The voltage really depends on the distance at the spark gap. I did read somewhere that the current at the collectors is around 10 microamps or less though. Of course, if you have a spark then the spark contains a much higher amount of current over a brief time.
I think I can build my own now, after watching your other video on how to build one. I ended up knowing that you can use a film disk 📀. But I won't build one Cus. am lazy😅
One of the clearest and best-animated science videos I’ve seen. Fantastic!
I was about to run away from this video half way through. So many educational vids like this go from simple elementary explanations to quantum physics equations in a matter of seconds. But this video was a steady incline of new information that even I could grasp after a few drinks. Thank you so much for this!
So finally after 2 years, the video is here!
Yup! I wrote a Hackaday article about it last year and that lead me to new ideas that made me try again.
@@RimstarOrg Where were you when I was in high school? If you'd been around to explain it then I might actually have passed sciences and physics
Wowww......
These have existed for like 50 years. If you really wanted to know how they work, you could have just Googled it
And 4 years later it’s still being viewed
thank you so much for all of your hard work to get me to understand electricity on the fundamental level. I really appreciate this channel a lot.

Great video, excellent explanation. But you have forgotten to clarify an important point:
How does the tension in the Leyden jars continue to increase?
After all, the electrons in the increasingly negatively charged jar must repel the electrons from the collector at some point, unless the tension at the collector keeps increasing to overcome this hurdle (and vice versa for the positive charges).
The explanation for this phenomenon is hidden in the capacitor formula's:

The well known capacitor formulas are: C = εA/d and C=Q/V.

As a result, the (negative) voltage (V) across this capacitor must increase accordingly, and is always higher (lower) than the voltage across the Leyden jar.
In theory, if there were no discharge at all (which is impossible) , the tension between the two jars could rise to infinity.
I built a Wimshurst machine myself a few years ago. Maybe I will make a nice video with a detailed explanation concerning the build and theory.
In the mean time you can see it sparking here: th-cam.com/video/QrFva1FmDhk/w-d-xo.html
This is amazing, Thanks for explaining this marvellous piece of machinery, It helps my research.🙏👍👍
nice. that really helped me understand. thank you.
Nice video sir...
Very easy to understand.. Thank you
Thank you for your great video!
im here because of a band with the same name as the maschine but that was a wonderful lesson perfect midnight knowlege thank you!!
Excellent content. Love the detailed animations
nice video it helped me to understand the aparatus, thank you very much! but one thing is missing a bit. the charge at the opposite sectors must become continuosly higher because otherwise it would not accumulate in the leyden jars. the fact that at the beginning it have only ONE sector charged and it influences charge separation at TWO sectors on the other plate makes the over all electric field stronger. this two charged sectors then rotate further and influence even stronger charge separation on the other side sectors and so on. so the charge separation effect adds up every time the "new/higher " charge meets the opposite neutralizer, and therefore charge becomes alternately higher on the front side and back side and cycles clockwise and anticlockwise.
That's correct. The charge on the sectors builds but quite a bit. The limiting factor is the leakiness of the sectors. In the dark, they glow with corona at their sharp edges and with corona between them. You can also smell ozone. If you don't collect at least some of the charge at the collectors then it becomes hard to turn the crank due to the strong attraction between the opposite sectors which in turn is due to the amount of charge on them.
Thats impressive. I would Not think that you can feel the force on the crankshaft Wow
I must be slow. I don't understand how this generates a charge and why it keeps growing.
All I see in the description is a lot of capacitors and wires holding charges. If you put a charge on a capacitor and then start connecting it to other capacitors the charges move and distribute but they don't grow in magnatude. They just keep getting smaller as you spread the charge over more capacitors.
I can grasp how this acts as a charge "sorter" so random starting charges get sorted by the action of the neutralizer bars moving charges. But I don't get how those sorted charges can ever exceed the total starting charge.
So what is the mechanism that causes the the charge to grow larger in this device?
I understand the mechanical motion of the device is the source of the energy generating the charge but I don't grasp how this works.
And why are the collector's pointed air gaps? Why not use another wire and brush to collect the charge? And what keeps the charge in the liden jars from returning to the disk? I don't understand why there is a one-way flow at work there.
My friend is convinced that this device can be used as a source of free energy. "I can harness this, regulate it, and then store it so it can later be used to chrage my batteries!"
Im not sure how to explain how that is not exactly likely.
He feels he just has to start it and walk away. Then come back to full batteries.
That isnt true is it?@@CurtWelch
Wow, incredibly well made video and very informative. Thank you very much !!
Excellent description!!!!!
Thanks!
What a great explanation! Thanks.
Nice video, good explanation ! Thank you for sharing !!
This was awesome thanks
Awesome video
Great video! Would it work if the brushes have higher surface area and are very close to the sectors, but not touching them tho?
Thanks! I recall seeing some with contactless brushes. I don't recall what the brushes looked like though.
Nicely explained
Thanks for explanation.
SO well done!!
Hi RimstarOrg;
I have to comment a bit about where the energy is obtained to cause the separation of the charges and generate such high voltages.
The separation doesn't come about for free! Work must be done to do the separation.
The plates on the disks form capacitors, "variable capacitors".
1. The plate pairs when initially charged have relatively high capacitance between each other. The energy in this capacitor is E=(CV^2)/2.
2. The capacitance of this capacitor is inversely proportional to the distance between the plates.
3. As the disks rotate the capacitance deceases between the plates. Since the charge in this capacitor is constant the voltage increases the further they are separated.
It takes mechanical work to oppose the attractive force between the plates. This work converts relatively low initial voltages to substantially higher voltages.
Note! Power is Voltage * current, W=V*A.
The initial plate charging current is the same as the current being collected and delivered to the Leyden jar. But, since the voltage is much higher the delivered output power is much higher then the initial input power. The added power is caused by the mechanical work expended in turning the disks.

The best device explaination
NIce! I wanna make one so bad.
I made this video explaining how to make one using as simple parts as possible th-cam.com/video/puC6-UaT9Fk/w-d-xo.html. It's not powerful enough for a lot of the demonstrations shown in this video but it works. I plan on showing how to make one that is powerful enough though.
Nice presentation. Let me understand the operation enough to ask questions.
Why the capacitors continues to take charge and not saturate? or will the charge in capacitor flood back into the next charge carrier?
great question
I Have seen that one in an Electric museum in Denmark. Tange Elmuseum
Brilliant! I never knew they where as complex as that - the ones I played with as a boy in London's Science Museum are all mahogany and brass with most of the workings hidden away.
So the one on your bike - could you put a xenon strobe tube across the spark gap and have a headlight that made it look like everything was static? (pun intended)
Thanks! You'd have to hide the disks in a casing too, otherwise the spinning disks would also give it away.
THANKS !!
Another great video.
Thanks.
Thanks from Brazil. So... why do you need the Leyden jars instead of solely conect the colectors to the spheres?
The Leyden jars are for getting bigger sparks. They collect additional charge so that when the spark gap breaks down, the spark will have more charge (current) and so will be bigger and brighter.
Great video
Can you show us how to make an electrostatic motor & a cronus motor,
Please cause your idea is better than other’s
Super video!
Thank you so much!
Thanks. Ever play with a radial dirod? I remember reading about it as a kid.
How has he done those animations?, they look great.
Thanks! I use Blender, free 3D modelling and animation software from blender.org
good job, thanks!
How much power does it generate. Enough for a AAA battery, or for a cell phone, or can a 12 volt battery be charged 🤔
If for a 12 volt battery 🔋, how long to change it up from 7 volts to 12.5 ...???
Excellent video. Ty so very much.
Good voice and gate in speech.
I have a little bit of electronics knowledge but more basic and a tiny bit more in a few areas .
I took electronics in high school and been around a few guys who know it really good.
But I just have not retained it over the years. Old part now and slower these days.
I love energy and renewable energy, especially.
I did know a man many years ago that was Nick Teslas lab aid and associate who showed me things beyond belief, but he demonstrated them.
He had a few photos of him and Tesla and some papers they worked on.
He was real. The man was a little over 100 at the time I met him. He really liked me. I liked him a lot as well.
He passed on at 112 years of age.
That was over 20 years ago.
He was a church decon since about 1942, I believe his church certificate said.
So again ty so very much for sharing this knowledge ❤️ with us.
It's not really intended as a power generator. I takes the mechanical energy of turning the crank and turns it into electrical energy with an efficiency of only a few percent.
@@RimstarOrg ty so very much ❤️
@@RimstarOrg it was designed to create high voltages but power requires amperage also and it has very little of that as in Micro amps. I recently used it to power the tesla hairpin circuit or stout bar experiment with some wonderful results. But that being said i have not tried to hook a step down transformer to it to increase the amperage pulse when the gap fires..
very good explanation and animation!
just a small detail, you showed four negative charges flowing from a negative charged sector to a neutral charged one, but if it was like this,
what would stop the negative charges to flow back where they was before? after all, it would be like at the beginning.
I think the neutralizer instead works by equalizing charges between sectors, exactly like two caps in parallel reach almost the same voltage,
so in your animation only two of the charges should move.
The charged sector that's on the other disk is what stops the negative charges from flowing back where they were before. When the disk rotates a little more and the sectors are no longer being touched by the neutralizer then there's no path for the negative charges to flow back along. And the repulsion by the negative sector on the other disk is still on the other side long enough for the disk to rotate away from the neutralizer.
I first thought that four charges should move and then realized that it would be just two, like you said. That's when I was thinking like you, that the neutralizer was equalizing charge. But then when the destination sector was next rotated to where there was a neutralizer on the other disk, then it would have only the strength of two charges to repel with. So on the other disk, only one charge would move along that neutralizer to another sector, and so on, with the amount of charge moving around being less and less all the time. So I thought that can't be right. That's when I realized that the two sectors and the neutralizer are all electrically connected and the explanation I gave made sense.
Very nice explanation and animations indeed! For me the question is not so much why the charge does not flow back, but why it is completely flowing to the other sector in the first place. I would think that it would almost even out between the two sectors. Can you explain why it would flow entirely to the opposite sector?
You are the best merci beaucoup monsieur
Thank you for great explanation and visualizations.
There are 2 Questionable statements in video.
These are my clarifications:
Capacitor stores charge in dielectric, not metal plates. metal only used to shape a charge and conduct it.
Also charge never goes inside metal. Due to repellent effect it only can travel on metal surface.
2. Are electrons and protons real? it is just a model. In the ancient physics only positive charge particle exists. Negative charge is a luck of positive particles.
"Capacitor stores charge in dielectric" No, you can build capacitors without any dielectric material.
"charge never goes inside metal." Oh yes! It is inside all metals. Conduction electrons are everywhere in a metal. You are probably confusing direct current with alternate current, where there is a so called skin-effect.
Are electrons and protons real? it is just a model. Agreed, but what's the point with respect to what is said in this video?
I understand how this works, but nobody seems to mention the voltage multiplication effect of the contra-rotating discs. At school we were taught that Q=CV. When two plates are opposite, they have a fixed charge; as they move apart, the charge remains the same, but the capacitance is reduced, causing the voltage to increase proportionately. Once the plates are at maximum distance, the voltage increase is sufficient to enable the charge to 'bleed-off' to the leyden jars via the corona between the plates and the collector points. Have I misunderstood something here or just missed a point?
Hmmm... Interesting. I was aware of the voltage increasing as capacitor plates are separated but hadn't considered any part it may play in a Wimshurst machine. That voltage is between the plates but I guess since the collectors are capacitively coupled through the collectors then the voltage on that side would be affected too.
How much watts (voltage and current) does it produce every second?
That's hard to answer. The voltage really depends on the distance at the spark gap. I did read somewhere that the current at the collectors is around 10 microamps or less though. Of course, if you have a spark then the spark contains a much higher amount of current over a brief time.
I think I can build my own now, after watching your other video on how to build one. I ended up knowing that you can use a film disk 📀. But I won't build one Cus. am lazy😅
Very interesting! I thought it worked because of friction somewhere between disks. Such principle is difficult to guess himself
One day this will be understood by all interested, without the confusion of charged virtual particles, using only the dielectric fields
I got two words for you...
USS Enterprise.
The man built ships alright...
A working model of the USS Enterprise..
Great video ☺️
