Two resistances R_{1} and R_{2} are made of different materials the temperature coefficient of resistance of the material of R _{1} is ' \\alpha ' and that of material R _{2} is -\\beta . The resistance of series combination of R _{1}, and R _{2} will not change with temperature if {R_{1}}/{R_{2}} equals to

\frac{\\alpha+\\beta}{\\alpha-\\beta}

{\\alpha^{2}+\\beta^{2}}/{2 \\alpha \\beta}
