Farad
(redirected from Femtofarad)

farad (făr`əd) [for Michael Faraday Faraday, Michael , 1791–1867, English scientist. The son of a blacksmith, he was apprenticed to a bookbinder at the age of 14. He had little formal education, but acquired a store of scientific knowledge through reading and by attending educational lectures

], unit of electrical capacitance capacitance, in electricity, capability of a body, system, circuit, or device for storing electric charge. Capacitance is expressed as the ratio of stored charge in coulombs to the impressed potential difference in volts.

, equivalent to 1 coulomb of stored charge per volt of applied potential difference.
Farad
A standard unit of measurement for capacitors (capacitance). 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 and coulomb.
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 [′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 

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.

0 femtofarad per micron squared (fF/om2)] and high value (2.
The Model 4200-CVU instrument comes as a module that plugs into any available instrument slot of the Model 4200-SCS, allowing fast and easy capacitance measurements from femtoFarads (fF) to nanoFarads (nF), at frequencies from 10kHz to 10MHz.
The most attractive feature of this new series is its extremely low capacitance ratings of less than a picofarad, otherwise known as femtofarad.
