Definition

1. Noun:
   • A unit of elastance equal to the reciprocal of a farad: The "daraf" is a derived unit of measurement for elastance, which is the reciprocal of capacitance. It is defined as one inverse farad (F⁻¹).

Usage Examples

• Noun:
  • The elastance of the component was measured in darafs.
  • One daraf is equivalent to one per farad.

Advanced Usage

• The term "daraf" is a specialized technical term used almost exclusively in the fields of electrical engineering and physics. It is the unit for the physical quantity of elastance (symbol: S), which is the inverse of capacitance (C): S = 1/C.
• It is rarely encountered in general language and is considered a back-formation, created by spelling "farad" backwards.

Variants and Related Words

• Elastance (n): The electrical property for which the daraf is the unit; the reciprocal of capacitance.
• Farad (n): The SI unit of electrical capacitance, which is the reciprocal of elastance.

Synonyms

• Per farad: A descriptive phrase equivalent to one daraf.
• Reciprocal farad: Another descriptive term for the unit.

Notes

• There are no common idioms or phrasal verbs associated with this highly technical term.
