Ampere

ahd-5
  • noun. The basic unit of electric current, equal to one coulomb per second and equivalent to the current, flowing in two straight parallel wires of negligible cross section separated by a distance of one meter, that produces a force between the wires of 2.0 × 10−7 newtons per meter of length. The value of an ampere in the International System differs very slightly from that in the meter-kilogram-second-ampere system of units.

  • noun. The unit employed in measuring the strength of an electrical current. It is the current which flows through a conductor whose resistance is one ohm, and between the two ends of which the unit difference of potentials, one volt, is maintained.
