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.
