👉 "dkg" is a technical term in physics and engineering that represents the unit of electric current density. It is often used to represent the amount of charge per unit area flowing through an element, which is fundamental for many applications in electronics, electromagnetics, and materials science. In this context, "dkg" refers to the volumetric electrical conductivity (or permittivity) of a material, defined as: \[ \varepsilon_{\text{dkg}} = \frac
