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...
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.
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...
