far·ad 'fa(ə)r-.ad, 'far-əd n the unit of capacitance equal to the capacitance of a capacitor between whose plates there appears a potential of one volt when it is charged by one coulomb of electricity abbr. fFar·a·day 'far-ə-.dā 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 force acting 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 magnetic flux 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 SI units of capacitance, equal to the capacitance of a capacitor between the plates of which a potential difference of 1 volt appears when it is charged with 1 coulomb of electricity. Symbol: F.* * *
far·ad (F) (farґəd) [M. Faraday] the SI unit of electric capacitance; the capacitance of a condenser that charged with 1 coulomb gives a difference of potential of 1 volt. This unit is so large that one-millionth part of it has been adopted as a practical unit called a microfarad.
