Ground (electricity)
In electrical engineering, ground or earth is a reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth. Electrical circuits may be connected to ground for several reasons. Exposed conductive parts of electrical equipment are connected to ground, to protect users from electrical shock hazard. If internal insulation fails, dangerous voltages may appear on the exposed conductive parts. Connecting exposed parts to ground will allow circuit breakers (or RCDs) to interrupt power supply in the event of a fault. In electric power distribution systems, a protective earth (PE) conductor is an essential part of the safety provided by the earthing system. Connection to ground also limits the build-up of static electricity when handling flammable products or electrostatic-sensitive devices. In some telegraph and power transmission circuits, the ground itself can be used as one condu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthing System
An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the Earth's conductive surface, for safety and functional purposes. The choice of earthing system can affect the safety and electromagnetic compatibility of the installation. Regulations for earthing systems vary among countries, though most follow the recommendations of the International Electrotechnical Commission (IEC). Regulations may identify special cases for earthing in mines, in patient care areas, or in hazardous areas of industrial plants. In addition to electric power systems, other systems may require grounding for safety or function. Tall structures may have lightning rods as part of a system to protect them from lightning strikes. Telegraph lines may use the Earth as one conductor of a circuit, saving the cost of installation of a return wire over a long circuit. Radio antennas may require particular grounding for operation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ground And Neutral
Ground and neutral are circuit conductors used in alternating current electrical systems. The ground circuit is connected to earth, and neutral circuit is usually connected to ground. As the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely related. Under certain conditions, a conductor used to connect to a system neutral is also used for grounding (earthing) of equipment and structures. Current carried on a grounding conductor can result in objectionable or dangerous voltages appearing on equipment enclosures, so the installation of grounding conductors and neutral conductors is carefully defined in electrical regulations. Where a neutral conductor is used also to connect equipment enclosures to earth, care must be taken that the neutral conductor never rises to a high voltage with respect to local ground. Definitions Ground or earth in a mains ( AC power) electrical wiring system is a conductor that provides a low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Bass
In music, an ostinato (; derived from Italian word for ''stubborn'', compare English ''obstinate'') is a motif or phrase that persistently repeats in the same musical voice, frequently in the same pitch. Well-known ostinato-based pieces include classical compositions such as Ravel's ''Boléro'' and the ''Carol of the Bells'', and popular songs such as Donna Summer and Giorgio Moroder's "I Feel Love" (1977), Henry Mancini's theme from ''Peter Gunn'' (1959), The Who's "Baba O'Riley" (1971), and The Verve's "Bitter Sweet Symphony" (1997). Both ''ostinatos'' and ''ostinati'' are accepted English plural forms, the latter reflecting the word's Italian etymology. The repeating idea may be a rhythmic pattern, part of a tune, or a complete melody in itself. Kamien, Roger (1258). ''Music: An Appreciation'', p. 611. . Strictly speaking, ostinati should have exact repetition, but in common usage, the term covers repetition with variation and development, such as the alteration of an osti ...

Ground Term
In mathematical logic, a ground term of a formal system is a term that does not contain any variables. Similarly, a ground formula is a formula that does not contain any variables. In first-order logic with identity, the sentence Q(a) \lor P(b) is a ground formula, with a and b being constant symbols. A ground expression is a ground term or ground formula. Examples Consider the following expressions in first order logic over a signature containing the constant symbols 0 and 1 for the numbers 0 and 1, respectively, a unary function symbol s for the successor function and a binary function symbol + for addition. * s(0), s(s(0)), s(s(s(0))), \ldots are ground terms; * 0 + 1, \; 0 + 1 + 1, \ldots are ground terms; * 0+s(0), \; s(0)+ s(0), \; s(0)+s(s(0))+0 are ground terms; * x + s(1) and s(x) are terms, but not ground terms; * s(0) = 1 and 0 + 0 = 0 are ground formulae.

Grounds For Divorce
Grounds for divorce are regulations specifying the circumstances under which a person will be granted a divorce. Adultery is the most common grounds for divorce. However, there are countries that view male adultery differently than female adultery as grounds for divorce. Before decisions on divorce are considered, one might check into state laws and country laws for legal divorce or separation as each culture has stipulations for divorce. Grounds for divorce Cruel and inhuman treatment constitute as grounds for divorce. In a proper defense, acceptable differences enable the defendant to have the ability to arrange grounds for divorce. Some examples for grounds for divorce are: * Sexual harassment * Attendant circumstance * Adultery * Alcoholism * Disability * Desertion * Imprisonment * Domestic violence (Including physical, sexual, or mental abuse of the other spouse and/or the child/children of the couple.) The spouse that is responsible for committing these allegati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
