Why is the shock from static electricity usually not dangerous?

  1. Static electricity cannot flow through a person
  2. The flow of electrons lasts only a very short time
  3. The voltage of static electricity is always very low
  4. Static charges only move through dry air
Show answer

Correct answer: The flow of electrons lasts only a very short time

Static charges equalize between two objects in a moment, so the shock is brief and self-limited.
