Textbook Question
Chapter 17, Problem 15P
An electric field greater than about 3 x 106 V/m causes air to break down (electrons are removed from the atoms and then recombine, emitting light). See Section 17-2and Table 17-3. If you shuffle along a carpet and then reach for a doorknob, a spark flies across a gap you estimate to be 1 mm between your finger and the doorknob. Estimate the voltage between your finger and the doorknob. Why is no harm done?
