Metal Wire Suspended in an electric field, any current produced?

  1. Oct 19, 2011 #1
    I've read that the atmosphere has a gradient of 100 V/m as altitude increases. My question is, if I suspend a low resistance wire vertically so that each end of the wire resides in a differently charged region of the atmosphere, would a current be produced in this wire?

    The different electric charge means there will flow electric current through a wire which short circuit the difference.
