Resistance characteristics of tellurium and silver-tellurium alloys

The problem of correcting temperature errors in electrical instruments with copper windings is explained and the high electrical efficiency obtainable by correcting these errors with series resistors having negative temperature coefficients of resistance is noted. A method is described for making such resistors of tellurium and of silver-tellurium alloy. Tests at various loads are described as a result of which the suitability of these resistors for various applications is determined.
