Question #187615

What is the temperature coeefficient of resistance of a piece of wire having a resistance of 12. 85 ohm at 30 degrees celcius and 6.85 ohm at 0 degrees celcius. what will be its resistance?

Expert's answer

"R_2=R_1(1+\\alpha(T_2-T_1))\\\\12.85=6.85(1+\\alpha(30-0))\\\\\n\\alpha=0.0292\\ K^{-1}"
