Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge.

For modeling the effect of static discharge on sensitive electronic devices, a human being is represented as a capacitor of 100 picofarads,
Charged to a voltage of 4,000 to 35,000 volts.
When touching an object this energy is discharged in less than a microsecond
