A coil of wire has a resistance of 37.800 Ω at 27.800 °C and 44.400 Ω at 56.000 °C. What is the temperature coefficient of resistivity? Do not enter units.
Equation: R=R0[1+α(T-T0)]
then i plugged in number to make the equation look like this:
44.400=37.800[1+X(56.000-27.800)]
and i solve for X and i get X=.0402 and its wrong...
anyone see something i dont?
