Static electricity voltage

  • What we call "Static electricity" also has another name: "high voltage.". All of the familiar electrostatic phenomena which we encounter in everyday situations always involve voltages above 1,000V, and ranging up to around 50,000 volts at the most. If it attracts lint or raises hair, it's definitely over 1,000 Volts.

Static electricity can be just a few volts (that you might experience from a nylon carpet) - or tens of thousands from a lighting bolt !

The static charge in air typically breaks down in this way at around 10,000 volts per centimeter (10 kV/cm) depending on humidity. The discharge superheats the surrounding air causing the bright flash, and produces a shock wave causing the clicking sound.

Many electronic components are sensitive to electrostatic voltage as low as 30 V and current as low as 0.001 A — far less than one can feel, hear or see (Table 1). How many volts does it take to feel static electricity? 3,000 volts. How many volts can you feel? The human body feels a shock when the voltage is higher than about 3,500 volts.

This type of long electric spark can only exist when a high voltage is present. The shortest, tiniest spark requires about 500 volts. Big, nasty, painful sparks require lots more voltage, up to several thousand volts. But even when no sparks are jumping, there's still a high voltage between your charged body and the ground.

Most electronics operate as they are heavily stressed even though the voltage is only 5 volts on many instances. Around a shaped object this could vary even if the average voltage appears to be constant. In welding sets the striking voltage can be about 80 volts but the hold down voltage can be 15 volts and even lower with an experienced welder.
