abohm

abohm

9.9
A very small unit of electrical resistance equal to one billionth of an ohm
  • noun
  • /əˈboʊm/
  • Archaic
: abohm
  • The laboratory report expressed the results using the abohm as the resistance unit.

Examples

  • One abohm is a very small unit of resistance.

  • One abohm is many orders of magnitude smaller than a typical resistor's value.

  • In theoretical calculations, the magnetic wire's resistance was measured in abohms.

  • The resistance of the circuit was measured in abohms.

  • In the specialized field of electromagnetism, the small resistance of the wire was precisely calculated to be 5 abohms.

  • The engineer noted that a very low resistance, often in abohms, is important for high-frequency applications.

  • For accurate measurement in electrical experiments, we often use abohms to quantify very small resistive values.

Morphology

abohm = ohm (semi-transparent) = ab + ohm

The relation to 'ohm' is clear, but the prefix 'ab-' indicates the CGS 'absolute' unit system and the specific scaling (10⁻⁹) is technical and not inferable by an average learner.

Etymology

Abohm combines the prefix ab- meaning 'absolute' and ohm, the name for electrical resistance from the scientist Georg Ohm. In an old measurement system an abohm meant 'one billionth' of an ohm, so the word now names a very small unit of resistance.
