ampere

 (A) [am´pēr]
the base SI unit of electric current strength, defined in terms of the force of attraction between two parallel conductors carrying current.

Am·père

(ahm'pēr),
André-Marie, French physicist, 1775-1836. See: ampere, statampere, Ampère postulate.

am·pere (A),

(am'pēr),
1. The practical unit of electrical current; the absolute, practical ampere originally was defined as having the value of one tenth of the electromagnetic unit.
2. Legal definition: the current that, flowing for 1 second, will deposit 1.118 mg of silver from silver nitrate solution.
3. Scientific (SI) definition: the current that, if maintained in two straight parallel conductors of infinite length and of negligible circular cross-sections and placed 1 m apart in a vacuum, produces between them a force of 2 × 10-7 N/m of length.

am·pere

(A) (am'pēr)
1. The practical unit of electrical current; the absolute, practical ampere originally was defined as having the value of1/10 of the electromagnetic unit (see abampere and coulomb).
2. Legal definition: the current that, flowing for 1 second, will deposit 1.118 mg of silver from silver nitrate solution.
3. Scientific (SI) definition: the current that, if maintained in two straight parallel conductors of infinite length and of negligible circular cross-sections and placed 1 m apart in a vacuum, produces between them a force of 2 × 10-7 N/m of length.
