specific electrical contact resistanceThe electrical contact resistance (ECR) of copper (Cu-ETP R200, soft) contacts for resistance welding (RW) is characterized. ECR plays a major role in the RW process and provides local heat generation between the parts. A special determination method is used ...

CopperElement10.091.678 SilverElement9.5461.587 * = Steel alloy at 99.5 percent iron, 0.5 percent carbon Notice that the figures for specific resistance in the above table are given in the very strange unit of “ohms-cmil/ft” (Ω-cmil/ft), This unit indicates what units we are expected ...
If the resistivity of a potentiometer wire be ρ and area of cross-section be A , then what will be potential gradient along the wire View Solution Assertion: When the radius of a copper wire is doubled, its specific resistance gets increased. Reason: Specific resistance is independent of...
Nickel disilicide (NiSi2) was formed on (100) orientedn‐type Si‐molecular beam epitaxial layers (Si‐MBE) of various doping levels between 2×1016and 13×1018cm3and on substrates of 2×1019cm3. Very low contact resistances were found and a low Schottky barrier of φBn=0.49 V was derive...
