Farad Definition and Usage
The farad is defined as the capacitance of a capacitor that has a potential difference of one volt when charged by one coulomb of electricity. The farad is considered to be a very large capacitance value, and multiples of the farad are commonly used to measure capacitance in practical applications, though the farad is still used in some applications.
The farad is the SI derived unit for capacitance in the metric system. Farads can be abbreviated as F; for example, 1 farad can be written as 1 F.
Background and Origin
The farad was named in honor of British scientist Michael Faraday, and the term "farad" was initially proposed as a unit of electric charge, but later was redefined as a unit of capacitance. The initial unit of electric charge was later renamed as the faraday when the farad was changed to a unit of capacitance. The farad was officially adopted as the unit of capacitance in 1881.
