B Electricity through a wire.

  1. Nov 27, 2016 #1
    I have read that in 1729 Stephen Gray, in addition to generating static charges, sends, for the first time, electricity through a wire and coins the words insulator and conductor.

    What does he think he is sending though the wire, there is not yet a concept of atoms or electrons as we know them today?

    He didn't know what exactly it was. Some mysterious substance known as electricity. It was often seen as some kind of invisible fluid.
    If you want to get a better idea of how scientists back then thought about this subject you could look at some old texts.
    e.g. this chapter in a book from the 18th century describing Mr. Gray's experiments.
    Or this book consisting of letters written by Benjamin Franklin.

    People sent water through a pipe before anyone knew about atoms. This is really no different.
