  • Question regarding the term "Conductivity".

    Hi !

    When I say "conductivity" is that generally understood by the vast majority of the science-educated to mean "thermal" conductivity ?

    I already know there is a difference between electrical and thermal conductivity and though I realize it's tempting for you to give a novel-length discourse here, I know it would be for me, but I'm just looking for a simple YES or NO answer. This is similar to an opinion-based poll.

    BTW, here's the reason for my question. I was trying to take a nap , but my mind kept working and the question came up "I wonder if the density of metal has any affect on it's conductivity ?" So I got up and went to my computer to find an answer. Several links answered my question, but some simply used "conductivity" in their explanation, whereas others used "thermal conductivity".

    Thanks,

    I differentiate between the two because of the Wiedemann-Franz Law. It comes down to this: Both thermal and electrical conductivity depend on not just the mean free path of electrons, but also on electron mass and the free electrons per unit volume in the metal. This is basically the "Wiedemann-Franz" Law.

      Hi Todd,

      In the world of metal detectors, this is the conductivity that matters.

          Question regarding the term "Conductivity".

          Sorry, had I given the subject more thought, I would have realized that my question is inconceivable and ridiculous and I wouldn't have posted it.

          It should have been obvious to me that when someone uses the single term "conductivity", I should be able to determine whether they meant electrical conductivity or thermal conductivity by the context in which the term was being used.

          Thanks for your replies.
