This video explains how to use a Leiden Jar or Leyden Jar. It also provides examples of experiments and demonstrations.

I really appreciate the fact that you can disassemble this one and the explanation that the majority of the charge is on the dielectric.

I instantly wondered if you could charge multipul plastic cups with one setup then use the stored power on one cup then disassemble it and put the next one in and use the energy stored on it so on and so forth. As long as you dont wipe the charge off them.

Great. The Leiden jar disassembly experiment is always a great one to demo especially when you have put a good amount of charge on it! Good that you show students this 'capacitor' as it rarely sees the light of day in modern physics teaching.

Very nice video, I am currently working on doing an instructional video on constructing a homemade jar but am in the research stage to make sure I understand the concept as much as possible before moving into the next step. I didn't really learn anything new from this video as I've already looked into this quite extensively, but I think you did a very nice job on it. Good quality and quick, thank you.

The energy is not in the charge separation, which is proven by the fact that you can touch the two metal conductors together and there is no discharge (with the insulator or dielectric removed). The energy is stored in the dielectric itself, in the form of an electric field. Though an alternate theory is that the energy is stored in the dielectric as a distortion of the internal magnetic fields.

Why is the exterior metal positive and the interior metal negative? (Or vice versa.) Answering that question would go further to explain matters. Also why do many Leyden jar constructions use water inside the jar?

Remember that electric charge is present only when negative electrons are separated from positive protons. However the charge is generated, you are left with an abundance of electrons on one surface and protons on the other, thus negative and positive. You can charge a Leiden jar, or most other types of capacitors, with either polarity connected to one side or the other. If you touch the inside element with the positive charge, the outside element always becomes negative, and vise versa. The water or other fluids inside early Leiden jars just served as the inner conductor, and can be replaced with conductive metal. Aluminum foil is a cheap and easy material for making the plates of a capacitor, and a sheet of plastic kitchen wrap or even waxed paper between them makes a fine dielectric.

".. very much like a capacitor." A Leyden jar is precisely a capacitor, just an early form. The jar is composed of two conducting elements (the metal cups) separated by an insulator (the plastic cup). This both describes and defines a capacitor.

Nice demonstration. Can you please explain why you touch the inner cylinder with an insulator whereas the outer cylinder is touched with barehand.

Long copper pipes grounded hold charge, instead of the charge in the atmosphere getting so large it needs to spark, instead it naturally grounds. Lord knows why no one is trying this

1:45 how was his body the souce of outside charge??? Aren't these metals suppose to have equal but opposite charge? What if the vande graff generator produced more charge compared to his body?? Also how did his body even produce charge? Sure it's a conductor but like ehhh???? I am so confused someone please explain!!!

@grego1451 2 жыл бұрын

His body is conductive, making a path for the electrons to leave the outside metal piece, giving the metal a positive charge.

@martinesimmonds5590 2 жыл бұрын

You said it yourself, "charge can't move on an insulator". What, then allows "The charge" to manifest as a useful means of electrification? Charge your diaelectric glass, plastic or distilled water, it will hold millions of volts, just keep it away from most metals. Redo the experiment and travel with only the Dialectric material to reveal your experiment. You'll always get a spark. This experiment has been done, if not hundreds of times, thousands of times. Conductive and Non Conducive materials are now inverted. Explain?

Can ANYONE explain WHY this one works without "Water" inside of it like literally ALL the other Leiden Jar designs I see on KZfaq? Like for example this funny twit in this video: kzfaq.info/get/bejne/rtCHYMykzLXNmqc.html As you can see like ALL the others he uses water with "Salt" to make it conduct electricity, they ALL seem to say the water is "Required" for a Leiden Jar to work, yet the one in this video has no water! WHY & HOW??? In the link I just gave he also claims a " van der graaf generator" can NOT charge a Leiden Jar, so WTF??

The setup acts as a capacitor, a capacitor is made up of two conductive metal surfaces (or plates), in between the two metal surfaces we place a dielectric material(plastic in this case), which will get charged and store an electric charge when the conductors/metal plates are electrically charged. In this video you have the layered materials [metal cup + plastic cup + metal cup] so, conductor + insulator/dielectric + conductor. In the other videos using water you have [metal foil + plastic cup/bottle + salted water], so conductor + insulator/dielectric + conductor. Its the same principle, its just that, for the inside of the cup/bottle, water is used as a conductor instead of a metal cup as in this video.
