1. [AMPS] Water dielectric? (score: 1): Author: Peter.Chadwick@zarlink.com (Peter Chadwick); Date: Fri, 3 Aug 2001 08:33:51 +0100; Of course, you couldn't use water if the cap had DC on it. Eventually, it would leach something out of the cap that would cause some conduction, and then you would get electrolysis. The problem with; /archives//html/Amps/2001-08/msg00024.html (6,931 bytes)
2. [AMPS] Water dielectric? (score: 1): Author: wc6w@juno.com (Radio WC6W); Date: Mon, 30 Jul 2001 10:41:35 -0700; Yes! ... and that brings to mind an old thought that I never fully explored. Water has a dielectric constant of about 80! I don't know the dissipation constant or loss factor. It seems, on the surfa; /archives//html/Amps/2001-07/msg00370.html (7,973 bytes)
3. [AMPS] Water dielectric? (score: 1): Author: 2@vc.net (2); Date: Mon, 30 Jul 2001 19:12:22 -0700; However, water absorbs carbon-dioxide from the air - which forms carbonic-acid, which is conductive. /\ so try it, Marv. - R.

4. [AMPS] Water dielectric? (score: 1): Author: w7ti@dslextreme.com (Bill Turner); Date: Tue, 31 Jul 2001 05:09:00 -0700; _________________________________________________________ Or, if not water, some non-conductive liquid. Don't have a dielectric chart handy, but there must be something suitable. Interesting thought; /archives//html/Amps/2001-07/msg00373.html (7,242 bytes)
5. [AMPS] Water dielectric? (score: 1): Author: phil@vaxxine.com (Phil (VA3UX)); Date: Tue, 31 Jul 2001 08:27:19 -0400; Transformer oil (or nearly any mineral oil) would work quite well. The dielectric constant typically is just over 2.0, and the voltage insulating characteristics are excellent. A good application wou; /archives//html/Amps/2001-07/msg00374.html (8,126 bytes)
6. [AMPS] Water dielectric? (score: 1): Author: W8JI@contesting.com (Tom Rauch); Date: Tue, 31 Jul 2001 10:11:43 -0400; When you look around and see the industry avoiding a method there is almost always a good reason. In this case they are probably concerned about loss of Q and heating of the component. Dissipation f; /archives//html/Amps/2001-07/msg00378.html (8,383 bytes)
7. [AMPS] Water dielectric? (score: 1): Author: wc6w@juno.com (Radio WC6W); Date: Tue, 31 Jul 2001 07:41:30 -0700; One more thought for the morning... A fixed plate capacitor could be made variable by immersing it in a combination of (pure) water and silicone. Those fluids won't mix. And by controlling the level; /archives//html/Amps/2001-07/msg00379.html (7,706 bytes)
