Ampere (A)
Definition: The ampere (symbol: A) is the SI base unit of electric current, defined as the constant current that, if maintained in two straight parallel conductors of infinite length and negligible circular cross-section placed one meter apart in a vacuum, would produce a force equal to 2×10⁻⁷ newtons per meter of length.
History: Named after André-Marie Ampère, one of the founders of electrodynamics. Originally defined in 1881 through electrolysis, it was redefined in 1948 based on the force between wires, and again in 2019 as part of the SI redefinition using the elementary charge.
Current use: Fundamental to all electrical measurements, used in circuit design, power systems, and electronics. The standard unit for measuring current flow in everything from household appliances to industrial machinery.
Kiloampere (kA)
Definition: A kiloampere (symbol: kA) equals one thousand amperes (10³ A). This large unit measures substantial currents like those in power transmission.
History: Developed for industrial-scale electrical applications as power systems expanded in the early 20th century.
Current use: Used in power distribution (substation transformers handle kA currents), industrial electrolysis, and lightning research (a lightning strike averages 30kA).
