1. A transient or continuous conduction of electricity through a gas by the formation and movement of electrons and ions in an applied electric field.
2. The flow of electricity through a gas, resulting in the emission of radiation that is characteristic of the gas and of the intensity of the current.
3. The removal of a charge from a battery, capacitor, or other electric-energy storage device.
4. The passage of electricity through a gas, usually accompanied by a glow, arc, spark, or corona.

1. An electric lamp in which the light comes from an electric discharge between two electrodes in a glass tube.
2. A lamp in which light is produced by an electric discharge between electrodes in a gas (or vapor) at low or high pressure.
3. A lamp that uses the transmission of an electric current through a gas or vapor to produce illumination. Neon, mercury and argon lamps are examples of electric-discharge lamps.
4. A lamp whose light is produced by current flow through a gas or vapor in a sealed glass enclosure.

Examples of these lamps include argon glow, mercury-vapor, neon glow, and sodium-vapor.

An evacuated enclosure (removal of gases and vapors) containing a gas at low pressure, through which current can flow when sufficient voltage is applied between metal electrodes in the tube.

The movement of a visible, or invisible, stream of charged particles away from a body that has been charged to a sufficiently high voltage.

A metal-cutting process in which high-frequency discharges from a negatively charged metal tool remove metal from the work piece by electroerosion.

There is no electrolyte, but the work is submerged in oil to flush away eroded particles and to delay each spark until peak energy is built up.>

1. A luminous discharge produced by a high-frequency electric field in a gas-filled glass tube with no internal electrodes.
2. An electric discharge generated by placing a discharge tube in a strong, high-frequency electromagnetic field.

An instrument consisting of an airtight quartz tube that holds the material to be analyzed.

When a high-frequency electrostatic field, generated by microwaves, is applied to the tube, it emits energy of a wavelength that is identical to that of the contained material.

A form of discharge produce by a perforated-wall hollow cathode operating under conditions of pressure, voltage, and geometry which is usually associated with the abnormal glow discharge.

1. The process of machining which is performed by electric sparks in a non-conductive liquid intervening substance.
2. A process by which materials that conduct electricity can be removed from a metal by an electric spark.

It is used to form holes with different shapes in materials that have poor machine operations.

The following methods can be used for protecting appliances and circuits against electrostatic discharges:

• Making surfaces on packages and containers for transporting vulnerable instruments conductive to prevent or to dissipate static buildup.
• Grounding conductive work surfaces.
• Requiring handlers to wear grounded, conductive wrist straps and conductive outer garments.
• Maintaining at least fifty percent relative humidity and active air ionization (static charges) in the work zone.

Susceptibility or sensitivity to the damage of a circuit or an appliance to damage or destruction by electrostatic discharges.

Equipment for simulating or imitating the discharge of static electricity from the human body or a naturally occurring discharge.

The movement of static electricity from a non-conductive surface which can damage or destroy semiconductors and other circuit components.

Static electricity can build on paper, plastic, or other non-conductors and be discharged by human skin (a finger) contact.

It can also be created by scuffing or rubbing one's shoes on a carpet or by brushing a non-conductor.
