Italic capital Z is the symbol for "impedance." 4, record 1, English, - electrical%20impedance
Record number: 1, Textual support number: 2 OBS
Impedance (Z) is measured in ohms (symbol: [capital omega]). It may be shown in (a) polar form: value of Z in ohms at a given phase angle in degrees or radians; or in (b) rectangular form: (resistive component) + j(reactive component) both in ohms. The symbol "j" indicates that the reactive component is in quadrature with respect to the resistive component. 4, record 1, English, - electrical%20impedance
Record number: 1, Textual support number: 3 OBS
Due to the reactive component, impedance is frequency dependent. 4, record 1, English, - electrical%20impedance

Le Z (majuscule italique) est le symbole de l'impédance. 4, record 1, French, - imp%C3%A9dance%20%C3%A9lectrique
Record number: 1, Textual support number: 3 OBS
On mesure l'impédance en ohms (symbole : [oméga majuscule]). 4, record 1, French, - imp%C3%A9dance%20%C3%A9lectrique
Record number: 1, Textual support number: 4 OBS
L'impédance est habituellement une grandeur complexe, c'est-à-dire composée d'une partie réelle (la résistance - R) et d'une partie imaginaire (la réactance - X) : Z = R + jX exprime l'impédance sous forme rectangulaire, le symbole «j» indiquant la partie imaginaire (en quadrature). Si l'on résout l'équation, on obtient Z (en ohms) à l'angle donné par la tangente X/R. 4, record 1, French, - imp%C3%A9dance%20%C3%A9lectrique
