Definition

1. Noun:
   • A unit of electrical charge: An abcoulomb is a unit of electrical charge in the centimeter-gram-second (CGS) electromagnetic system of units. It is defined as the charge transported by a constant current of one abampere in one second. One abcoulomb is equal to ten coulombs, the standard SI unit of charge.

Usage Examples

• Noun:
  • The textbook defined the abcoulomb as a CGS unit of charge.
  • An abcoulomb is equivalent to 10 coulombs.

Advanced Usage

• The abcoulomb is a non-SI unit that is largely obsolete in modern scientific contexts, having been superseded by the coulomb in the International System of Units (SI). It is primarily encountered in historical or specialized technical literature.

Variants and Related Words

• Abampere (n): The corresponding CGS unit of electric current. One abcoulomb is the charge transferred by one abampere in one second.
• Coulomb (n): The SI unit of electric charge, equal to the charge transported by a constant current of one ampere in one second. One abcoulomb equals 10 coulombs.
• Statcoulomb (n): The CGS electrostatic unit of charge, used in the CGS electrostatic system, distinct from the abcoulomb used in the CGS electromagnetic system.

Synonyms

• CGS unit of charge: A descriptive synonym indicating its system of measurement.
• Electromagnetic unit (emu) of charge: Another term specifying its place in the CGS electromagnetic unit system.
