The text discusses the theory of electrical residue in the Leyden jar, as presented by R. Kohlrausch. It describes the experimental investigation into the formation of electrical residue in the jar, leading to the conclusion that the previously accepted explanation is unlikely to be correct. A new law for the formation of electrical residue is proposed, which can be applied practically. The text explains that when a Leyden jar is charged, the voltage at its knob decreases over time, and this decrease is not solely due to electrical loss to the air but may also be attributed to the formation of an electrical residue. The experiments involved measuring the charge over time using a sine electrometer and a multiplier, and the results showed that the curve of charge decrease resembles a parabola but is not perfectly linear. The text also discusses the concept of electrical residue, which is the portion of charge that remains in the jar even after discharge, and how it can be measured and analyzed. The experiments revealed that the electrical residue is not uniformly distributed and depends on factors such as the size and shape of the jar, the material used for the coating, and the presence of a binding agent. The study concludes that the electrical residue is primarily influenced by the thickness of the glass and the material properties of the jar. The findings suggest that the electrical residue is a significant factor in the behavior of the Leyden jar and that further research is needed to fully understand its nature and behavior.The text discusses the theory of electrical residue in the Leyden jar, as presented by R.
