Sense Resistors

  1. Jul 1, 2010 #1
    In a 4-wire (kelvin) measuring system, why are there "sense" resistors? I understand that because there is very little current on the sense line there is no voltage drop. What purpose do they serve?

    Where are the sense resistors exactly? In a Kelvin 4-probe you run a constant current through a test resistance and then measure voltage drop across it.
