lederstrøm
Lederstrøm is a term used in physics and electrical engineering to describe the flow of electric charges through a conductive material due to an electric field. In common usage it corresponds to conduction current, or drift current, the component of electric current carried by mobile charge carriers such as electrons (and holes in semiconductors) under the influence of an electric field. The conventional direction of lederstrøm is the direction in which positive charges would move; in metals electrons actually drift in the opposite direction.
At the macroscopic level, the current density J is related to the electric field E by Ohm’s
In different materials, lederstrøm can comprise more than a single mechanism. In dielectrics and time-varying fields,
Lederstrøm is a foundational concept in circuit analysis, conductor theory, and solid-state physics, underpinning the operation
