Ikkeohmisk

Ikkeohmisk is a term occasionally used in speculative and interdisciplinary discussions to refer to systems that do not follow Ohm's law, in which current is not proportional to voltage. The coinage blends the word for "not" with a form derived from Ohm's law. It is not a standard term in physics, and most references treat it as a descriptive label rather than a formal category.

In function, ikkeohmisk systems exhibit nonlinear current–voltage relationships, impedance that varies with frequency and temperature, memory effects, and sometimes threshold behavior. Real-world analogs include diodes and transistors, certain complex materials, and memristive devices where conduction pathways change with applied fields. The term is often used to emphasize nonlinearity without specifying a particular mechanism.

History and usage: The concept appears primarily in speculative literature and informal discussions about novel materials and advanced circuits. It is not widely adopted in mainstream physics or engineering; researchers typically prefer precise descriptors such as nonlinear I–V characteristics, memristive behavior, or diodic conduction.
