érintkezésiellenállás
érintkezésiellenállás refers to the electrical resistance that occurs at the interface between two conductive materials when they are brought into contact. This resistance arises from imperfections on the surfaces of the conductors, such as microscopic irregularities, dirt, or oxidation layers. When these surfaces touch, the actual contact area is much smaller than the apparent area, leading to a higher resistance than would be predicted by the bulk resistivity of the materials alone.
The magnitude of érintkezésiellenállás is influenced by several factors, including the materials' surface roughness, the applied
érintkezésiellenállás is a critical parameter in the design and performance of electrical connectors, switches, and relays.
