Question 8.Q.17: What is the coefficient of resistance per degree Celsius of ......
What is the coefficient of resistance per degree Celsius of a material, if the resistance is 2246 Ω at 63°F and 3074 Ω at 405°F?
Step-by-Step
\begin{matrix} R_{2} = R_{1}(1 + \delta R\left\{342 × 5/9\right\} ) \\ 3074/2246 = 1 + 190\delta R \\ \delta R = 0.3686/190 = 1.94 × 10^{-3} Ω/°C \end{matrix}
