AMP   (ā'ěm-pē')  Pronunciation Key 
Short for adenosine monophosphate. An organic compound that is composed of adenosine and one phosphate group. It is one of the nucleotides present in DNA and RNA, and is also the fundamental component of ATP and ADP. During certain cellular metabolic processes, AMP forms from ADP when the latter loses a phosphate group, and AMP forms ADP by acquiring a phosphate group. Chemical formula: C10H14N5O7P.

amp (ampere) [(am-peer)]

A unit of electric current. One ampere corresponds to a certain number of electrons passing a fixed point each second.

Note: A typical household's electrical supply includes a total of 120 to 200 amps; a typical house circuit carries 15 to 50 amps.

amp

unit of electric current in the Systeme International d'Unites (SI), used by both scientists and technologists. Since 1948 the ampere has been defined as the constant current which, if maintained in two straight parallel conductors of infinite length of negligible circular cross section and placed one metre apart in a vacuum, would produce between these conductors a force equal to 2 10-7 newton per metre of length. Named for the 19th-century French physicist Andre-Marie Ampere, it represents a flow of one coulomb of electricity per second. A flow of one ampere is produced in a resistance of one ohm by a potential difference of one volt. See electric current.
