strömvägar

Stromväg translates to “current path” or “flow path” and denotes the route that a current or flow follows through a system from source to sink. The term is used in several disciplines, most commonly in electronics, fluid mechanics and physiology, to describe the path that carries charge, fluid, or signaling.

In electrical engineering, the stromväg is the conductive path that connects a voltage source to a load, including wires, components and contacts. A circuit may offer one or several stromvägar, such as a series path or multiple parallel paths. The distribution of current among parallel paths is governed by impedance and described by Ohm’s law and Kirchhoff’s circuit laws. The integrity of the stromväg depends on proper insulation, contacts and component condition; faults can open, short, or create unintended paths, with consequences for safety and performance.

In fluid mechanics and aerodynamics, the term is used informally for the route a fluid particle follows, analogous to a streamline or pathline. In steady flows, streamlines coincide with particle trajectories, and visualizations show stromvägar through pipes, channels or around objects.

In physiology and biomedical contexts, stromvägar may describe routes for electrical signals or ionic currents through tissues, such as neural or cardiac conduction pathways, where changes in the path affect timing and synchronization.

Measuring and analyzing stromvägar helps assess conduction, continuity and flow, informing safe wiring, efficient energy use and accurate modeling of transport phenomena.
