A certain resistor has a resistance of 1.484 omega at 20 degrees celsius and a resistance of 1.512 omega at 34.0 degrees celsius. What is its temperature coefficient of resistivity?

ok..I used a temperature equation but I can't get the right answer. so maybe I am doing something wrong

  2. ok I used 1.512 = 1.484[1+ alpha (34-20)] and the answer in the back of my book isn't the answer I am getting

  3. That is the right equation.

    alpha= (1.512-1.484)/(14*1.484)

    check my thinking.
