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.
A galvanostat (also known as amperostat) is a control and measuring device capable of keeping the current through an electrolytic cell in coulometric titrations constant, disregarding changes in the load itself.
Paschen's law is an equation that gives the breakdown voltage, that is, the voltage necessary to start a discharge or electric arc, between two electrodes in a gas as a function of pressure and gap length. [2] [3] It is named after Friedrich Paschen who discovered it empirically in 1889. [4]
Stirring the solution between cyclic voltammetry traces is important in order to supply the electrode surface with fresh analyte for each new experiment. The solubility of an analyte can change drastically with its overall charge; as such it is common for reduced or oxidized analyte species to precipitate out onto the electrode. This layering ...
Because exchange of W bosons involves a transfer of electric charge (as well as a transfer of weak isospin, while weak hypercharge is not transferred), it is known as "charged current". By contrast, exchanges of Z bosons involve no transfer of electrical charge, so it is referred to as a "neutral current". In the latter case, the word "current ...
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] A static electric charge can be created whenever two surfaces contact and/or slide against each other and then separate.

Voltage-current characteristics of electrical discharge in neon at 1 torr, with two planar electrodes separated by 50 cm. [dubious – discuss] A: random pulses by cosmic radiation B: saturation current C: avalanche Townsend discharge D: self-sustained Townsend ...
Lightning's abrupt electric discharge is accompanied by the emission of light. Noise and electromagnetic interference — Unwanted and usually random disturbance in an electrical signal. A Faraday cage can be used to attenuate electromagnetic fields, even to avoid the discharge from a Tesla coil.
