### Noun

- Unit of electrical current in electromagnetic and Gaussian cgs systems of units, equal to 10 amperes in SI units.

# Extensive Definition

The abampere (aA) is the basic electromagnetic unit of
electric
current in the
centimetre gram second system of units. One abampere is equal
to ten amperes in the
SI
system of units. An abampere of current flowing in a circular path
of one centimeter radius produces a magnetic field of 2 π oersteds at the center of the
circle.

The other units in this system related to the
abampere are:

- abcoulomb -- the charge that passes in one second through any cross section of a conductor carrying a steady current of one abampere
- abhenry -- the self-inductance of a circuit or the mutual inductance of two circuits in which the variation of current at the rate of one abampere per second results in an induced electromotive force of one abvolt
- abohm -- the resistance of a conductor that, with a constant current of one abampere flowing through it, maintains between its terminals a potential difference of one abvolt
