hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

Basically im having a little problem with linearity on this coursework. First off i did a simple resistance against temperature circuit in series, then i was told to put this in a potential divider circuit,so id measure the voltage output of the thermistor and see how this was affected by resistance and temperature change. I was told that this would produce more linear results,although i cant understand why. Also instead of using trial and error to bundle a pair of resistors together to get good linearity ,is there another way to predict which combination of resistors will produce the most linear results. Also in my conclusion on my different combinations of resistors,instead of just saying that it looks quite or not very linear,is there a way to prove that its linear, and also to prove which is the most linear,because for some graphs its hard to tell.
