In linguistics, grammar is the set of structural rules governing the composition of clauses, phrases, and words in any given natural language. The term refers also to the study of such rules, and this field includes morphology, syntax, and phonology, often complemented by phonetics, semantics, and pragmatics.
American Wire Gauge (AWG) is a U.S. standard set of non-ferrous wire conductor sizes. The gauge means the diameter.
When the gauge number increases, the wire diameter decreases. Stranded wire which is commonly used in audio visual applications has an AWG which is determined by the total cross-sectional area of the conductor, which determines its current capacity and electrical resistance.
