farad, the practical unit of capacity for electricity, in the electromagnetic system of units.
farad, the unit of electrical energy, so called from faraday.
The farad being inconveniently large for practical use, one-millionth of a farad, called a microfarad, is generally adopted.
The capacity of a condenser which would contain a charge of one coulomb under one volt pressure is the farad.
Since the farad is far too large for practical purposes a millionth of a farad, or microfarad, whose symbol is mfd., is used.
As this unit is inconveniently large, for practical applications the unit microfarad—millionth of a farad—is employed.
The condensers used in the above experiment have a capacity of one microfarad, or one millionth of a farad.
The practical unit of capacity is called the micro-farad, the real unit is the farad, and takes its name from faraday.
unit of electric capacity, suggested 1861, first used 1868, named for English physicist Michael Faraday (1791-1867). Related: Faradic.
farad far·ad (fār'əd, -ād')
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.
