ab- aΩ

A basic unit of electric current in the meter-kilogram-second system: One abampere is equal to ten amperes in the SI system of units, or the Système International [d'Unités], or the International 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.

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 and, as a consequence, the square of the speed of light appears explicitly in some of the equations interrelating quantities in this system.

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

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 electromagnetic unit of capacitance equal to 10⁹ farads (1,000,000,000 F or 1 GF): This very large abfarad is usually limited to applications in medical terminology:

The abfarad was named after the English physicist Michael Faraday who contributed to the study of electromagnetism, the physical interaction that occurs between electrically charged particles; and electrochemistry, the branch of physical chemistry that studies the relationship between electricity, as a measurable and quantitative phenomenon, and identifiable chemical changes.

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 or an electrical generator that produces direct current.

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 which is 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: When the scientists met, they exchanged notes about their theories of various applications of abhenries.

The term, abhenry, was 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 was the basis of the electrical telegraph.

Formerly, an electromagnetic unit of conductance; replaced by the absiemen: An abmho is a segment of the calculation of the centimetre-gram-second scale implemented to measure the capacity of a material to transmit electricity.

The centimeter-gram-second unit of electrical resistance equal to one billionth of an ohm: Albert found out that the equipment used in the university laboratory could accurately calculate the abohms so he could know more about their accuracy.

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

The siemens 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 and active in Great Britain as Sir Charles William Siemens. With his brother Ernst, he established many early electrical-engineering projects and manufacturing facilities.

The centimeter-gram-second electromagnetic unit of electric field strength: In his physics class in college, Timothy learned about the advolt per centimetre and what it was applied to.

1. 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.

2. The unit of electromotive force in the electromagnetic centimeter-gram-second system: One abvolt equals 10^-8 volts in the absolute meter-kilogram-second system.

The centimeter-gram-second unit of power: The power unit is equivalent to the power dispelled when 1 abampere moves across a possible discrepancy of 1 abwatt, or one ten thousandth of a milliwatt.
