electrostatic unit of charge
The quantity of electrical charge which repels an equal charge at a poiont in a vacuum at a distance of one centimeter with a force of one dyne.
1. A system of electrical units, based on the centimeter, gram, and second, in which a unit electric charge is by definition such that two units of the same sign placed one centimeter apart in vacuo (vacuum) will repel each other with a force of one dyne.
Units in the system are usually characterized by the prefix stat-, as statampere, statvolt, etc.
2. A centimeter-gram-second system of electric and magnetic units in which the unit of charge is that charge which exerts a force of one dyne on another unit charge when separated from it by a distance of one centimeter in a vacuum.
Other units are derived from this definition by assigning unit coefficients in equations relating electric and magnetic quantities.
