stat-, prefix|stæt|
[f. static a. and n.]
Used in combination with the names of the practical electrical units to form the C.G.S. electrostatic system of units, as statampere, statcoulomb, statfarad, statgauss, statohm, statvolt.
[1903A. E. Kennelly in Trans. Amer. Inst. Electr. Engin. XXII. 534 In a comprehensive system of electromagnetic terminology, the electric C.G.S. units should also be christened... They might be denoted by the prefix abstat. Thus the C.G.S. electric unit of e.m.f. would be the abstatvolt.] 1920Proc. Amer. Philos. Soc. LIX. 365 Be is the electric flux density in ‘statgausses’. 1925W. H. Timbie Elements of Electricity xvi. 584 A statcoulomb is a small unit of charge, one coulomb being equal to 3 × 109 statcoulombs. 1932S. S. Attwood Electric & Magnetic Fields i. 19 The unit of potential is an erg per statcoulomb and is called the statvolt in the electrostatic C.G.S. system. 1937H. L. Curtis Electr. Measurements ii. 11 The prefixes ab and abstat were proposed by Kennelly... The latter has generally been shortened to stat. No one of the proposed names has been adopted by any international organization. 1939J. B. Whitehead Electricity & Magnetism vi. 62 The name of the electrostatic unit of capacitance is the statfarad. One farad is equal to 9 × 1011 statfarads. 1958Condon & Odishaw Handbk. Physics a–9/2 The cgs unit of charge is called the esu or the statcoulomb. It is the unit defined by using dynes of force and cm of distance and adopting 4πε0 = 1. The corresponding unit of current is called the statampere, defined as the flow of one statcoulomb per second. Ibid. a–11/1, 1 statohm = c2/109 ohms..with c = 2·997930 × 1010 cm/sec. 1963Jerrard & McNeill Dict. Sci. Units 12 In recent years the prefix stat has sometimes been used to denote electrostatic units, thus 1 stat volt = 300 practical volts, 1 stat ampere = (1/3) × 10-9 ampere. This prefix is an abbreviation for abstat which was proposed for electrostatic units at the same time as ab was suggested for electromagnetic units. |
