Electrostatic units - electrostatic units

Japanese: 静電単位系 - せいでんたんいけい

A system of units that uses electric quantity defined by Coulomb's law as a base unit in addition to length, mass, and time. Abbreviated as esu, which is the abbreviation for electro-static unit. In the CGS electrostatic unit system, in addition to centimeter, gram, and second, the dielectric constant of a vacuum is a dimensionless quantity with a value of 1, and each of two equal electric quantities that are 1 cm apart in a vacuum and exert a force of 1 dyne on each other is defined as an electric quantity of 1 CGS electrostatic unit. → Gaussian unit system / Electromagnetic unit system → Related topics International units | CGS unit system

長さ，質量，時間のほかに，クーロンの法則によって定義される電気量を基本単位とする単位系。electro-static unitの頭文字をとってesuと略記。CGS静電単位系では，センチメートル，グラム，秒のほかに，真空の誘電率を値１の無次元量として，真空中で1cmの距離にあって互いに１ダインの力を及ぼす相等しい二つの電気量のおのおのを1CGS静電単位の電気量と定義する。→ガウス単位系／電磁単位系
