1. A unit of electric current in the centimeter-gram-second (CGS) electromagnetic system, equal to 10 amperes.
Usage: technical; physics; largely obsolete; replaced by the ampere in modern SI units

Examples

• The abampere was used in early electromagnetic measurements before the adoption of SI units.
• One abampere equals exactly 10 amperes in the modern electrical system.
• Historical physics texts often reference currents measured in abamperes.
• The CGS system defined the abampere as a fundamental unit of current.
