Creative Beading

Does potential difference change in a thermistor when temperature changes?

The circuit is simply a bead thermistor connected to a multimeter set to detect resistance, the bead thermistor is kept in a beaker with water of varying temperature (From boiling to warm)

It is linear because you are taking a log of the resistance. In thermistors, the resistance changes exponentially, so in order to get a straight line fit, we must take the log(resistance).

It’s funny but your hearing is the same, we hear on an exponential scale, that is why on older hi-fi’s with VU meters, they are actually using a log scale.
