Re: Oh, a warning about playing with glass & charge.... (fwd)

Forwarded message: > Date: Sun, 22 Nov 1998 10:05:41 -0800 > From: Tim May <tcmay(a)got.net> > Subject: Re: Oh, a warning about playing with glass & charge.... > And when you do your "...and then take away one of the copper plates" > experiment, you'll find that force is needed. Force times distance is > energy. The energy to pull one of the plates away equals the 0.5CV^2 energy > no longer stored in the capacitor. This is true ONLY if the dielectric doesn't touch either plate and is simply used to increase the storage capability (via Gauss' Law) of the capacitor over an air gap type of the same physical structure. The reason you have this force is the induced charge on the surface of the dielectric and the electrostatic attraction this causes with the charge on the plate. If the plate ACTUALY TOUCHES there is NO INDUCED CHARGE via Gauss's Law, it's a REAL charge stored on the surface of the insulating dielectric and the plate remains NEUTRALY charged. Why is there no induced charged? Because as you place charge on the conducting plate it induces a charge via Gauss' Law on the dielctric. Since the metal has outer orbital electrons available (which an insulator doesn't) the charge in the plate gets transported to the surface of the insulator and bonds there (remember unlike charges attract) with the induced charge. Why does the charge storage increase because of the dielectric? The electrical moment of the atoms is greater than that of the air. This is another reason the charge once deposited on the dielectric surface will stay there when the plate is removed. If you go back and look at the examples in your physics books that your basing your position on you'll find that in EVERY case there is an air gap between the plates and the dielectric. Remove the air gap and the behaviour of the charge and hence it's explanation changes accordingly. > The energy stored is not stored either on the plate or on the insulator. It > is in the electric field. Q: Where does the electric field come from Tim? A: The charges (ie electrons and protons) that are sitting on the surface of the dielectric (where the di- comes from). The electric field strength is a measure of the wavelength of the photons those two contrary sets of particles are bouncing back and forth between themselves. Q: Explain why the charge sitting on the surface of that dielectric will stay on the metal plate when the metal plate is removed. The metal plate is a conductor so as it is removed it effectively carries the charge of the part of the dielectric that it still retains contact with. Why would that e- choose to move TOWARD a ne- charge when it's sitting there with an opposite charge already in a minimum energy configuration? A: It won't. To do so violates the minimal energy requirements of the system as well as the standard behaviour of charges (ie like repel, opposite attract). Another experiment.... Try removing the metal foil when there is a charge and when there isn't. You won't find an appreciable difference. As to the energy required to remove the foil, yes force times distance is energy and it's the energy requisite to overcome the inertia of the metal foil. There is also a small additional force caused by Gauss' Law because the the distance between the e- (for example) stored on the dielectric and the metal plate will form a 'virtual' charge on the surface of the plate. However, since the plate itself is neutral (by definition) there will be a contrary charge on the opposite side. Hence, you won't loose a single coulomb of charge to the metal plate. You can check this by using either an electronic charge meter (1-800-OMEGA if you're interested) or you can use a gold leaf electrometer. If the charge varies as Tim claims then the angle between the leaves should change (ie get smaller). It won't. As to the force, the maximal force will occur when the plate is removed as a single piece perpendicular to the surface of the dielectric. If you roll or peel it off it will for all intents and purposes come free effortlessy because you won't have to fight the electrostatic force. -------------------------------------- < Cu + ------------------------------------------ -------------------------------------- < Cu - ------------------------------------------ -------------------------------------- < Cu + ------------------------------------------ -------------------------------------- < Cu - NOTE: there is NO air gap between the glass and the Cu sheeting. I use normal old cinter blocks to press them together as tightly as I can. Another experinment: Build the stack as shown above and remove each later one at at time with and without charge. Note the behaviour of the metal plate. It will tend to go with the glass plate that is being removed. Because of induced charges via Gauss' Law the foil will tend to go with the glass plate as it's removed. --------------------------------------------- ------------------------------------------- Cu + --------------------------------------------- As the top plate is removed the air gap will force a virtual charge to build up on the surface of the foil. As a consequence an opposite and equal charge will build up on the other side of the foil and it will be + and in opposition to the + charge already sitting on the bottem glass plate. The induced charge on the top of the Cu will be - and will be attracted to the + charge on the bottem of the top plate. This of course assumes you're using very thin foil. If it's very thick at all you won't see this because of gravity. I tend to use very heavy foil so that I don't get shocks from these various induced fields when I'm handling the plates. Be sure to use heavy rubber gloves. Rubbermaid kitchen gloves intended for industrial washing are sufficient unless you're going to use a high voltage and charge.

No Subject

I'm sorry if this is gnawing at old bones for you, but I recently heard from a rather paranoid, anonymous source here in Hungay that PGP was compromised, Zimmermann sold out to the Feds, all versions except possibly early DOS versions of PGP have back doors in them. He is also claiming that the CIA have already provided the backdoor-key to PGP 5.0 to the Hungarian Secret Services. Is he being too paranoid, or what? The reason I am asking cypherpunks, which I realise is not really a list dedicated to PGP, about them, is that their credentials to my mind would be sufficient to discredit. I have heard this rumour in sufficiently bogus intellectual contexts before (Cyberconf8, if that rings a bell to anyone - wouldn't blame you if it didn't) where it seemed blatantly obvious that it was entirely unfounded, as the people who were spreading it could not recognise code if they saw it, and seemed only an attempt to appear to be in the know. This source, however, seems different. Can I have some reassurance, please? And could you possibly suggest how someone unable to check the code themselves could go about authenticating a version of PGP? It is fated to become a rather important issue here soon. thank you holist

http://www.wired.com/news/news/business/story/16374.html AOL's E-Stamp of Approval Wired News Report 12:20 p.m. 19.Nov.98.PST Is it time for stamp collectors to go online? America Online (AOL) and E-Stamp, an online postage firm, said on Thursday they will make Internet postage service available to customers of AOL, CompuServe, AOL.COM, and AOL's Digital City. AOL and E-Stamp's service will allow customers to securely purchase postage online and print "digital stamps" on envelopes, labels, or documents using their personal computer and a standard printer. Customers must first install E-Stamp software. They can then buy postage by credit card, electronic fund transfer, or check. Thanks!
