Quelle est la formule mathématique liant la tension, la résistance et l'intensité dans un circuit électrique ?
La tension dans un circuit électrique est égale au produit de la résistance et de l'intensité, soit U = R x I.
La résistance dans un circuit électrique est égale à la tension divisée par l'intensité, soit R = U / I.
L'intensité dans un circuit électrique est égale à la tension divisée par la résistance, soit I = U / R.
