Meanings
-
A unit of electrical current, the standard base unit in the International System of Units; colloquially amp. Abbreviation: amp, Symbol: A
If the volt, ampere and ohm were taken as the absolute units, the practical units would be the ampere, begohm and begavolt, names just as convenient as ampere, coulomb and farad.
1900, Journal of the Franklin Institute, volume 149, page 461:Definition: The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 x 10⁻¹⁹ when expressed in the unit C, which is equal to A s, where the second is defined in terms of Δν_(Cs). (The International Bureau of Weights and Measures)
