Temperature coefficient resistance of a thermistor
Experiment
The aim of the experiment is to find out how much the resistance in a thermistor changes as the temperature of the thermistor and its surroundings changes. To do this the thermistor will be placed in a beaker of water with a thermometer and the temperature of the water raised, the thermistor will be attached to a meter to measure the resistance. At regular intervals the temperature of the water will be taken and at the same time the resistance will be taken. This will show if the resistance of a thermistor increases or decreases as the temperature increases.
Apparatus:
For this experiment I will need:
* A thermistor
* A beaker (containing water)
* A tripod, gauze and Bunsen burner
