Daraf
Encyclopedia
The daraf is the unit of electrical elastance (symbol: F−1), the volt
age 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).
Volt
The volt is the SI derived unit for electric potential, electric potential difference, and electromotive force. The volt is named in honor of the Italian physicist Alessandro Volta , who invented the voltaic pile, possibly the first chemical battery.- Definition :A single volt is defined as the...
age across a capacitor after accepting an electric charge
Electric charge
Electric charge is a physical property of matter that causes it to experience a force when near other electrically charged matter. Electric charge comes in two types, called positive and negative. Two positively charged substances, or objects, experience a mutual repulsive force, as do two...

Farad
The farad is the SI unit of capacitance. The unit is named after the English physicist Michael Faraday.- Definition :A farad is the charge in coulombs which a capacitor will accept for the potential across it to change 1 volt. A coulomb is 1 ampere second...
