	Static Electricity Static Control explanation and techniques to control the phenomenon of static electricity and how ...
		Static electricity in the atmosphere remains at rest until the potential gradient, between clouds, reaches a level that causes the insulator between clouds, in this case air, to break down or fail, and lightning is created to equalize the potential gradient.
		Static electricity is generated by unbalancing the molecular construction of relatively non-conductive insulators such as plastics and paper.
		If the static charge is negative in polarity, the electrostatic field is negative and positive ions are generated via the grounded sharp ends of the induction device and the positive ions are attracted back to the static laden surface.

	Electrostatics - Wikipedia, the free encyclopedia
		The electric field (in units of volts per meter) is defined as the force (in newtons) per unit charge (in coulombs).
		Static electric generators, devices which produce very high voltage at very low current and used for classroom physics demonstrations, rely on this effect.
		Note that the charges associated with static electricity need not be still or "static." The presence of charge motions and electric current does not detract from the net charge, the electrostatic forces, nor from the sparking and corona discharge, or other phenomena.

	Webopedia: Static Electricity and Computers
		Whenever the casing of a computer is opened and its internal workings are exposed (to change a hard drive or add memory chips, for example), there is a danger of damaging the computer with the buildup of static electricity that is held by the human body.
		Microchip damage can occur if it is exposed to static electricity as low as 10 volts, and humans are not able to perceive static electricity until it has reached about 1,500 volts.
		Another way to ground the static electricity is to touch the internal metal frame of the computer's case while the computer is plugged into an electrical socket.

	high voltage misconceptions: static electricity
		Few people realize that "static electric" devices have taken over the electronics industry, or that PCs are made from microscopic electrostatic components, or that all the data in all the computers all over the world is stored as tiny patterns of electrostatic charges.

		When a battery or other electrical source is attached to a wire, which is connected to some form of resistance, (a light, a bell, a motor, etc.), and a circuit is completed back to the source or to ground, free electrons are released into the wire, creating an electrical potential or voltage.
		In his electromagnetic induction theory he stated that an electric current flows in a conductor if that conductor is in a moving magnetic field and is part of a circuit.
		If the electric current surges to a dangerous level, the metal in the fuse melts and the circuit is broken, preventing overheated wires in the walls of the house from starting a fire.
