ab- +

One abampere is equal to ten amperes in the SI system of units.

One abampere equals 10 amperes in the absolute meter-kilogram-second-ampere system.

The unit of magnetic moment in the electromagnetic centimeter-gram-second system.

The unit of current density in the electromagnetic centimeter-gram-second system.

In the electromagnetic centimeter-gram-second system of units, the unit of electric dipole moment.

The unit of electric charge in the electromagnetic centimeter-gram-second system, where one abcoulomb is equal to 10 coulombs.

In the electromagnetic cgs system, electrical current is a fundamental quantity defined via Ampère'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 electromagnetic centimeter-gram-second unit of volume density of charge.

The electromagnetic centimeter-gram-second unit of surface density of charge, electric polarization, and displacement.

An abfarad is an electromagnetic unit of capacitance equal to 10⁹ farads (1,000,000,000 F or 1 GF).

This very large unit is usually limited to applications in medical terminology.

A farad is a basic unit of capacitance in the meter-kilogram-second system; equivalent to the capacitance of a capacitor in which a charge of 1 coulomb produces a change of 1 volt in the potential difference between its terminals. Named for Michael Faraday.

Abhenry is a medical term referring to the centimeter-gram-second electromagnetic unit of inductance, equal to 10^-9 or one billionth of a henry (a standard unit of inductance in the meter-kilogram-second system), equivalent to that of an induced 1 volt in the presence of a current that is changing at a rate of 1 ampere per second.

Named for Joseph Henry (1797-1878), a U.S. scientist who discovered the electromagnetic phenomenon of self-inductance, and who also discovered mutual inductance, independently of Michael Faraday. His work on the electromagnetic relay wss the basis of the electrical telegraph.

Michael Faraday (1791-1867) was an English experimental scientist who was especially noted for his discoveries in electricity, including electromagnetic induction, the battery, the electric arc, and the dynamo.

His work on induction formed the basis of modern electromagnetic technology, and his work on electrochemistry laid the basis for this other important modern industry.

Faraday's law is a law of electromagnetic induction stating that the electromotive force induced in a circuit is proportional to the time rate of magnetic flux change linked with the circuit.

Formerly, and electromagnetic unit of conductance; replaced by the absiemen.

The centimeter-gram-second electromagnetic unit of conductance; one absiemen is the conductance at which a potential of one abvolt forces a current of one abampere; equal to 10⁹ siemens.

One siemen is the conductance at which a potential of one volt forces a current of one ampere and named for Karl Wilhem Siemens.

Karl Wilhem Siemens (1823-1883) was a German electrical engineer; active in Great Britain as Sir Charles William Siemens; with his brother Ernst, established many early electrical-engineering projects and manufacturing facilities.

The centimeter-gram-second electromagnetic unit of electromotive force.

One abvolt is the difference of potential between any two points when one erg of work is required to move one abcoulomb of electricity between them; equal to 10^-8 volts.

The centimeter-gram-second electromagnetic unit of electric field strength.

The centimeter-gram-second unit of power.
