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 ...
I-K arc discharge. 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). [1]
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]
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.
Also, macroscopic objects made of conductive elements can more or less easily (depending on the element) take on or give off electrons, and then maintain a net negative or positive charge indefinitely. When the net electric charge of an object is non-zero and motionless, the phenomenon is known as static electricity.
Some weakly electric knifefishes appear to mimic the electric eel's discharge patterns; this may be Batesian mimicry, to deceive predators that they are too dangerous to attack. [ 20 ] Weakly electric fish can communicate by modulating the electrical waveform they generate.
The I-K region is a region of arc discharge; the plasma is concentrated in a narrow channel along the center of the tube; a great amount of radiation is produced. In cold cathode tubes, the electric discharge in gas has three regions, with distinct current–voltage characteristics: [1] I: Townsend discharge, below the breakdown voltage. At low ...
Developmental bioelectricity is a sub-discipline of biology, related to, but distinct from, neurophysiology and bioelectromagnetics. Developmental bioelectricity refers to the endogenous ion fluxes, transmembrane and transepithelial voltage gradients, and electric currents and fields produced and sustained in living cells and tissues.
