Farad

 

the unit of electrical capacitance in the International System of Units and in the meter-kilogram-second-ampere (MKSA) system of units. The symbol for the farad, which was named after M. Faraday, is F. One farad is the capacitance of a capacitor in which a charge of 1 coulomb produces a potential difference of 1 volt between the plates. The unit of capacitance in the centimeter-gram-second (cgs) electrostatic system is 1 cm = (109/c2) F ≈ 1.113 × 10–12F, where c is the numerical value of the speed of light in a vacuum in cm/sec. In practice, the following fractional units are used more frequently than the farad: the microfarad (µLF), which equals 10–6F, and the picofarad (pF), which equals 10–12F.

farad

[′fa‚rad]
(electricity)
The unit of capacitance in the meter-kilogram-second system, equal to the capacitance of a capacitor which has a potential difference of 1 volt between its plates when the charge on one of its plates is 1 coulomb, there being an equal and opposite charge on the other plate. Symbolized F.

farad

Physics the derived SI unit of electric capacitance; the capacitance of a capacitor between the plates of which a potential of 1 volt is created by a charge of 1 coulomb.

Farad

A standard unit of measurement for capacitors (capacitance). Named after the English physicist Michael Faraday, one Farad (F) is equal to an increase of one volt when a charge of one coulomb is applied. In microelectronics, measurements are typically in microFarads (mF) or picoFarads (pF). See capacitance, coulomb and Faraday cage.
