Answer to Question #166550 in Electricity and Magnetism for JayJay
Question #166550
A certain resistor has a resistance of 212.1Ω at 25⁰C and a resistance of 214.2 Ω at 50⁰C. What is its temperature coefficient of resistivity?
Expert's answer
"\\alpha=\\frac{\\Delta R}{R_0 \\Delta t},"
"\\alpha=\\frac{214.2-212.1}{212.1(50-25)}=(396\\cdot10^{-6})\u00b0C^{-1}."
