a unit of elastance equal to the reciprocal of a farad
Non SI approved unit proposed as the unit of electrical elastance. Probably not in serious use.
Origin: farad reversed.
The daraf is the unit of electrical elastance, the voltage across a capacitor after accepting an electric charge of 1 coulomb; it is the reciprocal of the farad. Proposed by Arthur Edwin Kennelly in 1936 as a backwards spelling of farad, the term daraf is not recognized by the SI.
