  Farad - Wikipedia, the free encyclopedia
The farad (symbol: F) is the SI unit of capacitance.
Since the farad is a very large unit, values of capacitors are usually in range of microfarads (μF), nanofarads (nF), or picofarads (pF).
The farad should not be confused with the faraday, an old unit of charge nowadays superseded by the coulomb.

Farad ist die SI-Einheit für die elektrische Kapazität.
Ein Farad ist eine relativ große Einheit, die meisten Kondensatoren haben in der Praxis Kapazitäten zwischen einigen Pikofarad (pF) und einigen Mikrofarad (μF).
Ein Kondensator hat die Kapazität von 1 Farad, wenn ihn ein Strom von 1 Ampere in 1 Sekunde auf eine Spannung von 1 Volt auflädt (1 F = 1 \frac{A\cdot\mathrm{s}} {V}).

 FARAD gets new life in 2002 - January 1, 2002
Although FARAD is recognized as contributing to humane food animal production and a safe food supply, the inability to secure adequate annual funding had resulted in serious cuts in the program's operations.
FARAD may be a victim of its own success, according to Dr. Alistair Webb of the University of Florida College of Veterinary Medicine, where he oversees the program database.
The purpose of FARAD is to prevent such problems by protecting U.S. food from harmful drug and pesticide contamination.

 FARAD
In un capacitore di 1 farad, una carica elettrica di 1 coulomb genera una differenza di potenziale pari a 1 volt.
Poichè il farad è un unità molto grande, i valori dei capacitori comunemente utilizzati in elettronica si esprimono in microfarad (μF), nanofarad (nF), o picofarad (pF).
Il farad non va confuso con il faraday, una vecchia unità di misura per la carica elettrica ora rimpiazzata dal coulomb.

 The Farad
The farad is a very large unit of measurement of capacitance.
Capacitance is a physical property of the capacitor and does not depend on circuit characteristics of voltage, current, and resistance.
A given capacitor always has the same value of capacitance (farads) in one circuit as in any other circuit in which it is connected.

 Farad - Term Explanation on IndexSuche.Com   (Site not responding. Last check: 2007-10-07)
A capacitor has a value of one farad when one coulomb of charge causes a potential_difference of one volt across it.
Its dimensions in SI units are: :C\cdot V^{-1} = m^{-2}\cdot kg^{-1}\cdot s^4\cdot A^2 SInce the farad is a very large unit, values of capacitors are usually expressed in microfarads (μF), nanofarads (nF), or picofarads (pF).
Multiples higher than the microfarad are rarely used in practice, even for large capacitances, so that a capacitance of 4.7×10-3F, for example, is usually written as 4700μF. The farad should not be confused with the faraday, an old unit of charge nowadays superseded by the coulomb.

FARAD maintains numerous databases, in which a wealth of pharmacokinetic and regulatory information pertaining to veterinary drugs, pesticides and other chemicals is stored.
In addition to the day-to-day running of the Access Center, we are continuously seeking improved mechanisms of estimating withdrawal periods through the development of algorithms and the application of population pharmacokinetic techniques.

 Howstuffworks "How Capacitors Work"
To store one AA battery's energy in a capacitor, you would need 3,600 * 2.8 = 10,080 farads to hold it, because an amp-hour is 3,600 amp-seconds.
If it takes something the size of a can of tuna to hold a farad, then 10,080 farads is going to take up a LOT more space than a single AA battery!
Obviously, it is impractical to use capacitors to store any significant amount of power unless you do it at a high voltage.

They are found in a variety of electronic components with a particular importance in amplifiers where they store a charge for later use outputting an electric signal or an electric current to drive speakers.
Farads are used to measure the amount of charge that can be stored.
Another commonly used term is microfarad meaning the measurement of the ability to store one millionth of a farad of electrical charge (micro means one millionth; 1/1,000,000).
