An electric field greater than about 3×106V/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.
1. Estimate the voltage between your finger and the doorknob.
2. Why is no harm done?
