That includes choosing a dielectric for it, the insulating material that goes between the plates. One dielectric material that I use a lot is paraffin wax which can\u00a0be found in art stores and is normally used for making candles. Another\u00a0is resin, the easiest to find being automotive resin used for\u00a0automotive body repairs.<\/p>\n<p>The problem is that you sometimes need to do the calculations for the\u00a0capacitor dimensions ahead of time, rather than just throwing something\u00a0together. And that means you need to know the dielectric constant of the dielectric material. That\u2019s something that the manufacturer of the paraffin wax that makes it for art stores won\u2019t know, nor will the manufacturers of automotive body repair resin. The intended customers just don\u2019t care.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Dielectrics are insulators that are used to separate the charged plates\u00a0in capacitors.
