Abampere
From Wikipedia, the free encyclopedia
The abampere (aA) is the basic unit of current in the centimetre gram second system of units. One abampere is equal to ten amperes in the SI system of units. The American Heritage Medical Dictionary defines abampere as "The centimeter-gram-second electromagnetic unit of current equal to ten amperes." [1]
In the electromagnetic CGS system, electrical current is a fundamental quantity defined via Ampere's law and takes the permeability as a dimensionless quantity (relative permeability) whose value in a vacuum is unity. As a consequence, the square of the speed of light appears explicitly in some of the equations interrelating quantities in this system.
The other units in this system are the:
- abcoulomb (charge),
- abfarad (capacitance),
- abhenry (inductance),
- abohm (resistance),
- abvolt (electric potential),
- abwatt (power).
