-Set circuit as shown
-Independent is temperature, dependent is current
-Control thermistor temperature with a hot water bath
-Cool it down with ice (remember reading this off an older paper's mark scheme)
-R is needed to increase resistance of circuit so reduce amount of current flowing through the circuit
-Large amount of current produces a heating effect which can affect temperature of the thermistor
-Also could be a hazard, especially if thermistor's resistance drops very low
-Plot V against T
-Temp of room can be measured by leaving the circuit out, taking the reading off the voltmeter and reading it off the graph (line of best fit)
