## 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) the base SI unit of electric current strength, defined in terms of the force of attraction between two parallel conductors carrying current.

## ampere (A)

[am′pēr]
Etymology: André-Marie Ampère, French physicist, 1775-1836
a unit of measurement of the amount of electric current. An ampere, according to the meter-kilogram-second (MKS) system, is the amount of current passed through a resistance of 1 ohm by an electric potential of 1 volt; in the International System (SI) of Units, an ampere is a unit of electric current that carries a charge of 1 coulomb through a conductor in 1 second. The standard international ampere is the amount of current that deposits 0.001118 g of silver per second when passed, according to certain specifications, through a silver nitrate solution. See also ohm, volt, watt.

## 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.
