abF 3
abF 3 :
The abfarad (abbreviated abF) is the unit of electromagnetic capacitance in the cgs (centimeter/gram/second) system of units. If a charge of one?abcoulomb (1 abC) produces a potential difference of one abvolt (1 abV) in a capacitance, then that capacitance is 1 abF. A capacitance as large as 1 abF is unknown. It is equivalent to 109 farads. The farad (F) is the standard unit of capacitance in the International System of Units (SI). Even this unit is large; a 1-F capacitor is almost never found in the real world. In practical applications, the microfarad (µF) and the picofarad (pF) are most often used to quantify capacitance; the abfarad is rarely seen in literature. For comparison, 1 µF = 10-6F and 1 pF = 10-12F. Thus, 1 abF = 1015F = 1021pF. Also See: Capacitance,Farad,Cgs or Small-Unit Metric System, and International System of Units (SI)
