Sommaire général

Régimes variables

II. Grandeurs électriques

1. Tension électrique

c. Représentation sur un schéma

Pour tenir compte des différences obtenues en permutant les bornes des appareils de mesure, la tension entre deux points d'un circuit électrique est représentée par une flèche.

Tension entre les points B et A notée `u_"BA"(t) = - u_"AB"(t)`.
