An electric field greater than about 3x10^6 V/m causes air to break down (electrons are removed from the atoms and then recombine, emitting light). If you shuffle along a carpet and then reach for a doorknob, a spark flies across a gap you estimate to be 1mm between your finger and the doorknob. Estimate the voltage between your finger and the doorknob.
