I- Rappel

Le conducteur ohmique, appelé aussi résistor, est un dipôle non polarisé caractérisé par une grandeur physique appelé

résistance. Cette grandeur se note R et son unité dans le système internationale est l’Ohm (Ω).

* Le conducteur ohmique permet de diminuer l’intensité du courant dans un circuit électrique. Son symbole normalisé est :

II-Loi d’Ohm
