Electrostatic discharge (ESD) is a sudden and momentary flow of electric current between two differently-charged objects when brought close together or when the dielectric between them breaks down, often creating a visible spark associated with the static electricity between the objects. ESD can create spectacular electric sparks (lightning ...
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge. The word "static" is used to differentiate it from current electricity, where an electric charge flows through an electrical conductor. [1]
In electromagnetism, an electric discharge is the release and transmission of electricity in an applied electric field through a medium such as a gas (i.e., an outgoing flow of electric current through a non-metal medium).
Permittivity and relative permittivity, the electric polarizability of materials. Quantisation of charge, the charge units carried by electrons or protons. Static electricity, stationary charge accumulated on a material. Triboelectric effect, separation of charges due to sliding or contact.
Static discharge is also a particular hazard in grain elevators owing to the danger of a dust explosion, [131] in places that store explosive powders, [132] and in many other cases. [133] Triboelectric powder separation has been discussed as a method of separating powders, for instance different biopolymers. [ 134 ]
An antistatic device is any device that reduces, dampens, or otherwise inhibits electrostatic discharge, or ESD, which is the buildup or discharge of static electricity. [1] [2] ESD can damage electrical components such as computer hard drives, and even ignite flammable liquids and gases. Many methods exist for neutralizing static electricity ...
An electrostatic-sensitive device (often abbreviated ESD) is any component (primarily electrical) which can be damaged by common static charges which build up on people, tools, and other non-conductors or semiconductors. [1] ESD commonly also stands for electrostatic discharge.
Natural observable examples of electric current include lightning, static electric discharge, and the solar wind, the source of the polar auroras. Man-made occurrences of electric current include the flow of conduction electrons in metal wires such as the overhead power lines that deliver electrical energy across long distances and the smaller ...
