FARAD

far·ad   (fār'əd, -ād')    n.   Abbr. F The unit of capacitance in the meter-kilogram-second system equal to the capacitance of a capacitor having an equal and opposite charge of 1 coulomb on each plate and a potential difference of 1 volt between the plates. See Table at measurement. [After Michael Faraday.]

farad 

Main Entry: far·ad
Pronunciation: 'fa(&)r-"ad, 'far-&d
Function: noun
: the unit of capacitance equal to the capacitance of a capacitorbetween whose plates there appears a potential of one volt when it is charged by one coulomb of electricity —abbreviation f
Faráaáday /'far-&-"dA/, Michael(1791–1867), British physicist and chemist. Faraday ranks as one of the greatest experimental scientists of all time. In the field of electricity he demonstrated in 1821 that the forceacting on a current-carrying wire in a magnetic field was circular and directed around the wire. In 1831 he discovered that an electromotive force can be induced in a circuit by varying the magneticflux linked with the circuit, and he built an elementary electric motor and dynamo. Faraday also stated the basic laws of electrolysis and introduced the terms anode, cathode,anion, cation, and electrode.

n.
The unit of capacitance in the meter-kilogram-second system equal to the capacitance of a capacitor having a charge of 1 coulomb when a potential difference of 1 volt is applied.

farad   (fār'əd)  Pronunciation Key  The SI derived unit used to measure electric capacitance. A capacitor in which a stored charge of one coulomb provides an electric potential difference of one volt across its plates has a capacitance of one farad.

farad

unit of electrical capacitance (ability to hold an electric charge), in the metre-kilogram-second system of physical units, named in honour of the English scientist Michael Faraday. The capacitance of a capacitor is one farad when one coulomb of electricity changes the potential between the plates by one volt. In terms of ordinary electric and electronic equipment, the farad is enormous, and capacitors are generally rated in microfarads (one microfarad equals 10-6 farad) or picofarads (10-12 farad).
