Connecting lug used as a current-sense resistor

摘要

A lug with relatively small resistance is provided that allows current to be determined between a source and a load by measuring the voltage drop across the lug. The voltage drop is sufficient to be above the electronic noise, and yet the resistance of the lug is low enough so that the heat produced by current flow is small compared with the heat generated by the source. The material comprising the lug is of a type and strength to be readily manufactured, and its resistivity varies by a relatively small amount with temperature.
