Definition of "Arcing" |
A luminous electrical discharge (bright, electrical sparking) through the air that occurs when high voltages exist across a gap between conductors. / Arcing is an electrical breakdown of a gas that produces an ongoing plasma discharge, resulting from a current through normally nonconductive media such as air. An arc discharge is characterized by a lower voltage than a glow discharge, and relies on thermionic emission of electrons from the electrodes supporting the arc. An archaic term is voltaic arc, as used in the phrase voltaic arc lamp. / Truth Table is a mathematical table used in logic specifically in connection with Boolean algebra, boolean functions, and propositional calculus to compute the functional values of logical expressions on each of their functional arguments, that is, on each combination of values taken by their logical variables,Enderton, 2001. In particular, truth tables can be used to tell whether a propositional expression is true for all legitimate input values, that is, logically valid. |
