Conductivity or specific conductance of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is siemens per meter (S/m). Conductivity measurements are used routinely in many industrial and environmental applications as a fast, inexpensive and reliable way of measuring the ionic content in a ...
The conductivity of a water/aqueous solution is highly dependent on its concentration of dissolved salts, and other chemical species that ionize in the solution. Electrical conductivity of water samples is used as an indicator of how salt-free, ion-free, or impurity-free the sample is; the purer the water, the lower the conductivity (the higher ...
The molar conductivity of an electrolyte solution is defined as its conductivity divided by its molar concentration: [1] [2] =, where κ is the measured conductivity (formerly known as specific conductance), [3] c is the molar concentration of the electrolyte.
Also called chordal or DC resistance This corresponds to the usual definition of resistance; the voltage divided by the current R s t a t i c = V I. {\displaystyle R_{\mathrm {static} }={V \over I}.} It is the slope of the line (chord) from the origin through the point on the curve. Static resistance determines the power dissipation in an electrical component. Points on the current–voltage ...
In 1921, solid silver iodide (AgI) was found to have had extraordinary high ionic conductivity at temperatures above 147 °C, AgI changes into a phase that has an ionic conductivity of ~ 1 –1 cm −1. [clarification needed] This high temperature phase of AgI is an example of a superionic conductor.
The following are Maxwell's equations without sources (which are treated separately in the scope of plasma oscillations), in Gaussian units: =; =; =; = +. Then = = = or = (+) which is an electromagnetic wave equation for a continuous homogeneous medium with dielectric constant () in the Helmoltz form = where the refractive index is () = and the ...

When a surface is immersed in a solution containing electrolytes, it develops a net surface charge.This is often because of ionic adsorption. Aqueous solutions universally contain positive and negative ions (cations and anions, respectively), which interact with partial charges on the surface, adsorbing to and thus ionizing the surface and creating a net surface charge.
