ELECTRICAL ENCYCLOPEDIA

Farad (unit) http://en.wikipedia.org/wiki/Farad   A farad is the charge in coulombs which a capacitor will accept for the potential across it to change 1 volt. A coulomb is 1 ampere second. Example: A 47 mA current causes the voltage across a capacitor to increase by 1 volt per second. It therefore has a capacitance of 47 mF. It has the base SI representation of s4·A2·m−2·kg−1. Further equalities follow:  Farad Definition http://www.thefreedictionary.com/farad   The unit of capacitance in the meter-kilogram-second system equal to the capacitance of a capacitor having an equal and opposite charge of 1 coulomb on each plate and a potential difference of 1 volt between the plates. See Table at measurement. History of Farad http://americanproxy.org/   The Farad was coined by Josiah Latimer Clark in the year of 1861, in honor of Michael Faraday, but it was for a unit of quantity of charge. Values of capacitors are usually specified in ranges of farads (F), microfarads (μF or MFD, one mill

Henry (unit) http://en.wikipedia.org/wiki/Henry_(unit)   In physics, and electronics, the Henry (symbol H) is the SI unit of inductance. It is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same time as Michael Faraday (1791–1867) in England. The magnetic permeability of the vacuum is 4π×10−7 H/m (henry per meter). Joseph Henry http://www.aip.org   Well into the nineteenth century American science existed, where it existed at all, either as a genteel pastime or as an adjunct to the urgent needs of the new nation—agriculture, navigation, exploration. The best research was usually done in fields serving these practical interests, and the closest approach to physics was work in positional astronomy, meteorology, geology and the like. Joseph Henry arose from this tradition and quickly surpassed it. Henry Conversion http://online.unitconverterpro.com   Online Unit Converter. Various henry conversion f
