What Does AA Stand For?
AA stands for Attoampere
Attoampere (AA) is a unit of electric current in the International System of Units (SI), equal to one quintillionth (10^-18) of an ampere. It is commonly used in scientific and engineering applications to measure extremely small currents, particularly in fields such as nanoelectronics and particle physics. The attoampere provides a precise means of quantifying minuscule electrical phenomena critical for advanced research and technology development.
