The origin of overvoltages
Electrostatic overvoltages (ESD) Electrically, a human being has a capacitance ranging from 100 to
300
picofarads, and can pick up a charge of as much as 15kV by walking on a carpet, then touch some conducting object and be discharged in a few nanoseconds, with a current of about ten Amperes.
