    heyyy
    I need to know what are the main factors that influence the electrical conductivity in earth materials such as fruit and/or veg. Anyone any ideaaasss???
    thanks :)
    ps. This is for backing up the choice of either potaoes or lemons having the highest ocnductivity of electricity.

    cross circular area of the conductor; if you think spuds are the answer. ;)

    You'll need to consider what the different charge carriers are and the chemical potential to conduct electrons in each case

    Water content.

    I haven't tried it, but I would doubt dried fruit would be a good conductor.

    Water itself is not a conductor though. It's the impurities which allows the electron flow.

    I said water content, not water. Pure non-conducting water would be rare, and the water in vegetables would definitely not be pure.

    lemons have citric acid so should be more conductive

    BTW gherkins get interesting when you put hight voltage through them

    Everything gets interesting once you put a high enough voltage through it. You can make a water blowtorch with high voltage (sorry don't have the video clip, but it has been done, and there is a video clip).

    But...let's get back to science......Why are covalent solvents such poor conductors?

    And what are Zwitterions ?
