摘要
1. A high-precision flat electric resistor having an adjustable resistance value and comprising a sheet of metal or metal alloy deposited on or bonded to a support comprising several electric, resistive, sinuous and interconnectable circuits, each of them being constituted by a series of electrical resistance filaments separated by grooves, some of the said resistive circuits being short-circuited by conductive strips of the metal or metal alloy of the sheet, these circuits being interconnectable by means of cut-out portions made in the conductive strips, the resistance value of a resistor having n electric circuits interconnected in serie being RTn and that of a resistor having n-1 electric circuits interconnected in series being RTn-1, characterized in that the ratio DELTA R = RTn - RTn-1 to the resistance value RTn-1 follows the relation : DELTA R/RTn-1 = 1.3...2n-1/2.4...2n K**2n where K is an adjustable numerical coefficient having a value smaller than 1.
