Electron current in metals

  1. Jun 29, 2015 #1
    we generally talk about electron current in metals.but when an electron leaves, it leaves a hole in its place.
    does the hole current really exist in metals?please explain the stuff.

    Sure, you can have positive hall coefficients in metals like cadmium.

    When current is flowing in a metal, there is not really a hole left behind as electrons are provided by the negative electrode of your source (battery or whatever).
