So at high school we were taught that the following table was normally used for such work. Dad also taught me the same thing. He sort of knew his stuff as he held engineering degrees from
Poland/France
Great Britain
Australia
https://en.wikipedia.org/wiki/Electr...d_conductivity
The table is a few pages down, but is identical to the one I still use today. Yes, I agree that conductivity and resistivity are equal and opposites of each other.
I have also stated that my writing skills are very 'strayan, so my meaning may have been misunderstood.
My apologies for any confusion.
With respect
Joe
