Physics Coursework The effect of temperature on the resistance of a thermistor Aim: The aim of this experiment is to find out whether temperature affects the resistance of a thermistor. Variables: * The temperature. * Type of ammeter. I will be investigating whether or not a change in temperature of water to find out whether or not it will affect the resistance of a thermistor. I will be keeping the following variable the same: * The power supply. I will be taking readings of the temperature, volts, amps and resistance. I will be using a digital voltmeter, ammeter and thermometer for more accurate results. I will also be repeating the experiment at least twice and getting an average. I will be measuring and recording my results in amps, volts, resistance and degrees Celsius. Apparatus: Stand Ammeter Bunsen burner Voltmeter Thermistor Thermometer Beaker Tripod Power pack Electric leads Diagrams: This diagram shows the electrical circuit involved: This diagram shows the apparatus set up: Definitions: Current- This is a measure of...
