WebNov 3, 2024 · This method is very useful for measuring contact resistance in complicated machinery assembles. The contact resistance is defined as the ratio the voltage across the contact to the current flown through a closed pair of contacts. It accorded with Ohm’s law. There is an interface between the metal 1 and metal 2. WebMeasuring static contact resistance verifies whether the resistance of current carrying contacts, in particular joints, allows the flow of rated current within specified losses. The resistance depends on contact surface properties which are the connection points on …
