QUE SIGNIFIE ELECTRIC DISPLACEMENT EN ANGLAIS
Champ de déplacement électrique
En physique, le champ de déplacement électrique, désigné par D, est un champ vectoriel qui apparaît dans les équations de Maxwell. Il explique les effets de la charge libre et liée dans les matériaux. "D" signifie "déplacement", comme dans le concept connexe de courant de déplacement dans les diélectriques. Dans l'espace libre, le champ de déplacement électrique est équivalent à la densité de flux, un concept qui garantit la compréhension de la loi de Gauss.
définition de electric displacement dans le dictionnaire anglais
La définition du déplacement électrique dans le dictionnaire est la densité de flux électrique quand un champ électrique existe dans l'espace libre dans lequel un diélectrique est introduit. D Aussi appelé: densité de flux électrique.
