Question about conductors, wires and lattice of ions

  1. Oct 15, 2012 #1
    Hi guys, sorry as this is probably a silly question. This isn't homework, but it's something I'm confused about in my GCSE course.

    If a lattice of ions can't conduct electricity when solid, then why can a wire (composed of these lattices (I think?)) conduct electricity?

    The electrons in a circuit collide with these lattices and create resistance and whatnot, I understand that. Sorry for the waste of time if it's an obvious answer!!

    thanks.

    It's because electrons can move in a metal. So the ions can stay immobile and you get a current.
