Constriction resistance
WebSynonyms for CONSTRICTION: compression, squeezing, contraction, condensing, constricting, condensation, contracting, squeeze; Antonyms of CONSTRICTION: … WebWher, two large conductors touch over a small circular area, there is a constriction resistance between them of p/2a, where a is the radius of the contact circle. This equation is very widely used in the design and study of electrical contacts. There is evidence, however: that contact between metals rarely, if ever, occurs in this way. ...

WebAs indicated in Fig. 2, the maximum constriction resistance R c, which accounts for the local temperature rise over the average surface temperature, is the only additional quantity that is needed for determining the maximum heat sink temperature. It can be accurately determined from the following correlation. WebAbstract. The relation between the area of contact and the constriction resistance which holds for a single circular contact spot is widely used in electric contact theory, although …
WebThe electrical contact resistance test is used for switching devices, cable joints as well as other connections. It can measure either the voltage drop or the resistance offered by the contacts or the resistance of the joints or connections. Consequences of Higher Contact Resistance .
