[Etymology: reverse spelling of farad] electric elastance (Metric) The elastance of a circuit in darafs equals the reciprocal of its capacitance in farads, so, for a steady current, equals the ratio of the rise in the potential produced between its plates in volts to the applied charge in coulombs.

Metric-m.k.s. (symbol usually D) F^-1 = V·C^-1, identically V·(A·s)^-1 and J·C^-2(= m²·kg¹·s^-4·A^-2 in base terms).

Metric-c.g.s. See abdaraf; statdaraf. See also practical unit.

The daraf is the unit of electrical elastance (symbol: F⁻¹), 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 (semordnilaps) of farad, the term daraf is not recognized by the SI (the preferred term being reciprocal farad).

$1 F^{-1} = \frac{1 V}{1 C}$
