    Try a 5 milli-ohm 5W resistor! I've used them in my design work to measure current ~20A. I might have a few lying around in my junk box too.

    High current shunts can be into the micro ohms. Of course they're shunts, not resistors.

    That would possibly be a +10 MHO conductor -vs- resistor...

    When our middle daughter was about six, she had a plate of cookies. I asked her if i could have a cookie, and she handed me one. I said, "You know how I hate odd numbers." She took her cookie back and said, "Zero is an even number, too!"

    Now you know.




    Best logic I've ever heard. LOL

    I'm not sure if that is strictly correct. Couldn't you have current flowing through a superconductor with zero resistance and therefore zero voltage?

    They also minimize stray capacitance and inductance, thereby managing complex impedance, not just resistance.
