elektronstrømmen
Elektronstrømmen, or electron current, refers to the flow of electric charge carried by electrons in a conductor. In most electrical circuits, electrons move from the negative terminal (cathode) toward the positive terminal (anode). The direction of conventional current is defined opposite to electron flow, from positive to negative, owing to the historical ambiguity in the early development of electricity theory.
The concept of electron current arose with the discovery of the electron in 1897 by J.J. Thomson.
Electron current is quantified in amperes (A), where one ampere equals one coulomb of charge passing through
In contemporary physics, electron currents underlie advanced technologies such as field‑effect transistors, quantum tunneling devices, and
