2. A unit of electrical current, the standard base unit in the International System of Units; colloquially amp. Abbreviation: amp, Symbol: A

   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)

   • 1900, Journal of the Franklin Institute, volume 149, page 461:

     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.
