(Latin: one, single; a word element for number 1)
2. To divide something into smaller parts or groups, or to become divided in this way.
2. Separated or having been separated; set at variance; alienated.
3. Something that has been divided into smaller parts or groups, or which became divided in this way.
Used as the motto of the United States, indicating that a single nation was made by uniting many states.
Three different systems of electric units are used:
- The electromagnetic unit.
- The electrostatic unit.
- The ordinary or practical units.
The commonly used practical units are the ampere or unit of current, the volt or unit of electromotive force, the ohm or unit of resistance, the coulomb or unit of quantity, the farad or unit of capacitance, and the watt or unit of power.
Units in the system are usually presented with the prefix ab-; such as, abampere, abvolt, etc.2. A centimeter-gram-second system of electric and magnetic units in which the unit of current is defined as the current which, if maintained in two straight parallel wires having infinite length and being one centimeter apart in vacuum, would produce between these conductors a force of two dynes (units of force) per centimeter of length.
Other units are derived from this definition by assigning unit coefficients in equations relating electric and magnetic quantities.
2. Any unit in the centimeter-gram-second system of units for measuring electricity and magnetism that gives a value of one to the magnetic constant; for example, the abampere, abfarad, abhenry, or the abvolt.
2. A microprocessor and memory with electronic maps, forming the central part of an engine management system or of subsystems; such as, a fuel injection or ignition system.
The gas flashes brilliantly when a capacitor is discharged through the tube.
2. A unit based primarily upon the force exerted between two electric charges.
3. An electric unit based primarily on the dynamic interaction of electric charges.
It is defined as a charge which, if concentrated on a small sphere, would repel with a force of one dyne which is a similar charge of one centimeter away in a vacuum.
