Abstract
Le procédé pour la fabrication de résistances électriques planes de haute précision consiste à graver sur une feuille de métal ou d'alliage 10 un circuit résistant 11 électrique sinueux puis à ajuster la valeur ohmique de la résistance en pratiquant dans la feuille 10 des découpes destinées à modifier la longueur du circuit. On grave sur la feuille une série de circuits résistants électriques annexes (A1 , ... B1 , ... C1 , ... D1,...) dont l'accroissement des valeurs ohmiques intrinsèques suit une progression géométrique et pour ajuster la valeur ohmique finale de la résistance, on pratique dans la feuille 10 des découpes telles que 19 destinées à mettre en série avec le reste du circuit, le ou les circuits résistants électriques annexes dont la valeur ohmique correspond à la valeur ohmique d'ajustage désirée pour la résistance. Application à l'ajustage de la valeur ohmique des résistances de haute précision.
