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 modelling 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 4000 to 35000 volts.
When touching an object this energy is discharged in less than a microsecond
Are you having a little trouble understanding this?
If so, the next photo should clear things up................................
