    Measuring resistance of thermistor in potential dividers

    Ahh ok. Hope I am right in saying heat energy? So a guess, does this mean the heat will affect the resistance output from the thermistor? That makes sense, so you use a potential divider circuit to eliminate that problem? I am not quite sure why... (Is it something to do with the other resistor...

    Measuring resistance of thermistor in potential dividers

    Right... Thanks for the help.. Im not really understanding what you mean by the first question. Yes I do know the equations.

    Measuring resistance of thermistor in potential dividers

    Why is this necessary? I just need to know what makes this circuit a better way to do it. But the current at say 20degrees was about 0.4 set at 20mA for potential divider. I didn't check the current for the other circuit. just had a resistance meter and thermistor.

    Measuring resistance of thermistor in potential dividers

    Hi there, first off I hope this is ok to post here. Quite a simple question. I have done an experiment simply to work out the resistance of a thermistor at different temperatures, I did a prelim with a simple circuit of just ohm meter + thermistor. Then I did the main one with a potential...
