Homework Statement
Well this isn't a homework problem, but I am writing a lab report for a lab we did concerning the change in resistance as a function of temperature.
Everything I have read says that the resistance in conductors should increase with temperature, but all of our data shows that resistance decreases as temperature increases. This was shown in a resistor, commercial resistor, diode, and copper wire. However, the resistance of an inductor DID increase as temperature increased. I don't know why all of our data doesn't support what I am learning. Nothing about our experiment would have yielded such results so I think I may be understanding it the wrong way.
The only reason I can think of is that our components were somehow semi-conductors because the resistance of semi-conductors decreases as temperature increases just like our data.
Anyone know what's going on?
