Basic conductor and current related question

  1. Feb 22, 2012 #1
    As we say that current is the flow of charges, but if we dye a conductor with red color and then connect the terminal with the dc source.

    Now as the current starts flowing through this conductor and we say current is the flow of electrons or charges then why the red color around the conductor doesnot start spreading?

    Thanking in anticipation!

    hi kambez! :smile:

    (what is it with you and colour? :wink:)
    the red colour comes from the atoms, and they don't move (and any electrons they lose to the current are replaced by other electrons from the current) :wink:
