The symbol for amps (amperes), the SI unit of electric current, is A.
In more detail:
-
Amps (Amperes): Amperes measure the rate of flow of electric charge. One ampere is defined as the current flowing through two parallel conductors of infinite length, negligible circular cross-section, placed one meter apart in a vacuum, that produces a force equal to 2 × 10⁻⁷ newtons per meter of length between them.
-
Symbol: The uppercase letter "A" is internationally recognized as the symbol representing amperes or amps. For example, you might see "5 A" on an appliance, indicating it draws 5 amperes of current.
