Physics A-Level coursework on thermistors!!Watch
"Investigate, using thermistor, how time varies with temperature for 50 degree c to 180."

The resistance of a thermistor decreases as the temperature increases.
Check this for yourself by placing the thermistor in a testube of oil along with the thermometer. Place this testube in a beaker of water and use a heater to heat the water. This will in turn heat the oil which the thermistor is measuring.
Periodically record the resistance and temperature, i.e at 1 degree intervals.
Plot the temperature as 1/T (temp in kelvin) against the log of the resistance (in ohms) and see how well it fits the straight line predicted by theory.
Hope this helps. If not, you've not lost anything!
Anyone have any thoughts?
hope ive helped some1!
