====Improving [[Precision]]====
: Use an [[ammeter]] with a greater [[resolution]]the same component for each repeat. Do not just use the same value of component as they may be slightly different from one another.: Use a low [[voltmeter]] with a greater [[resolutionElectrical Current|current]]and turn the circuit off between readings. This prevents the wires and components increasing in temperature which would increase resistance and affect future readings including repeat readings.

#Connect an [[ammeter]] in [[Series Circuit|series]] with the [[thermistor]] to measure [[Electrical Current|current]] through the [[thermistor]].
#Connect a [[voltmeter]] in [[Parallel Circuit|parallel]] with the [[thermistor]] to measure the [[Potential Difference|potential difference]] across it.
#Repeat steps 5-7 with the [[thermistor]] in a [[beaker]] of hot [[water]] around 40°C.
