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 ...
Dissipative: Materials with an electrical resistance between 1MΩ and 1TΩ Shielding : Materials that attenuate current and electrical fields Low-charging or Anti-static : Materials that limit the buildup of charge by prevention of triboelectric effects through physical separation or by selecting materials that do not build up charge easily.
[1] Dissipative antistatic bags, as the name suggests, are made of standard polyethylene with a static dissipative coating or layer on the plastic. This prevents buildup of a static charge on the surface of the bag, as it dissipates the charge to ground (i.e., whatever other surface it is touching).

A tornado may be thought of as a dissipative system. Dissipative systems stand in contrast to conservative systems. A dissipative structure is a dissipative system that has a dynamical regime that is in some sense in a reproducible steady state. This reproducible steady state may be reached by natural evolution of the system, by artifice, or by ...
between 2008 and 2012, better performance than 44% of all directors The Robert D. Storey Stock Index From January 2008 to May 2008, if you bought shares in companies when Robert D. Storey joined the board, and sold them when he left, you would have a -10.4 percent return on your investment, compared to a -4.0 percent return from the S&P 500.
The loss tangent is defined by the angle between the capacitor's impedance vector and the negative reactive axis. If the capacitor is used in an AC circuit, the dissipation factor due to the non-ideal capacitor is expressed as the ratio of the resistive power loss in the ESR to the reactive power oscillating in the capacitor, or
The 401(k) has been around for 46 years, and in that time, it has become the dominant workplace retirement plan employees of all ages use to save for their futures. Each generation has made its ...
