ABSTRACT:
A balanced wire resistor has two interconnected windings with different temperature coefficients. The electrical resistance of the wire resistor is determined only by the resistance values of the two windings. In a process for the production of the wire resistor, the wire length of a first winding of the newly to be wound wire resistance is calculated by using the measured wire length, as well as measured resistance values of the previously wound wire resistor. The wire length of a second winding of the newly to be wound wire resistance is determined by using the two measured wire lengths of the two windings, as well as measured resistance values of the previously wound wire resistor.
