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

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

However, water absorbs carbon-dioxide from the air - which forms carbonic-acid, which is conductive. /\ so try it, Marv. - R. L. Measures, 805.386.3734,AG6K, end -- FAQ on WW

_________________________________________________________ Or, if not water, some non-conductive liquid. Don't have a dielectric chart handy, but there must be something suitable. Interesting thought

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

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

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

/\ So make the plates out a good conductor. /\ good points, Mr. Rauch. If there had been something better, Joe Jennings would likely have chosen it over the vacuum dielectric in his variable capacit
