WebIn dilute solutions, the conductivity of the electrolyte solution is the sum of the conductivities of the ions in the solution, which can be expressed by the following equation: (20) (1) where κ is conductivity, ni is the number of ion i, qi is charge of ion i, and μ i is mobility of ion i. WebSolution conductivity actually regulates the tensile forces acting on ejected jets in an electric field. Here, the dielectric constant becomes another decisive parameter that needs to be deeply considered. More specifically, the higher dielectric constant of a solvent provides the higher conductivity of the resulting polymer solution.

Dielectric relaxation is the momentary delay (or lag) in the dielectric constant of a material. This is usually caused by the delay in molecular polarisation with respect to a changing electric field in a dielectric medium (e.g., inside capacitors or between two large conducting surfaces). Dielectric relaxation in changing electric fields could be considered analogous to hysteresis in changing magnetic fields (e.g., in inductor or transformer cores). Relaxation in general is a delay or lag in th… WebConductivity and Dielectric Constant of Dielectrics. 363 On the Variation with Frequency of the Conductivity and Dielectric Constant of Dielectrics for High-Frequency Oscilla tions.
