[QUOTE="guyvsdcsniper, post: 6588800, member: 686799"] [B]Homework Statement:[/B] Find Ro, a, and b. [B]Relevant Equations:[/B] R(T) = Ro (1 + aT + bT2 ) I am asked to find Ro, a, and b. Th problem states the values are determined by the measurements at the normal ice, steam and sulfur points. So I approached the problem by plugging the the temperature problems. For 0°C, Ro reduces to 7 ohms. Then for the other two non zero temperatures, it looks like I am left with a system of equations. I am a bit stumbled because the values associated for a and b of both equations arent factors of each other, so canceling out seems a bit trickier. I don't really recall running across a problem like this before. Am I approaching this problem correctly? If so what is a way to solve for a and b?[ATTACH=full]295642[/ATTACH] [/QUOTE]
