Web2.1 Constriction resistance The most basic and most well-known result is that, if two effectively semi-infinite bodies of resistivity r are in contact over a small circular area of radius a, then the constriction resistance is given by [2] R ¼ r=2a ð1Þ According to Greenwood [3], Holm developed this further, WebJul 8, 2024 · Instead, devices, connectors, and circuits are designed around the existence of contact resistance and—in most cases—are designed to prevent or mitigate the impact it might have. That being said, contact resistance is typically caused by three culprits: constriction, film resistance, and stress relaxation.
