Name: Ray Li Physics Coursework Aim: Effect of changing the temperature on the resistance of a thermistor I am going to find out has the temperature effects the thermistor' resistance in the circuit. Planning Method: 1) Clear the table and take off the needless thing 2) Use the wires to link all the equipment to complete the circuits. 3) Put about 25cm3 water in the beaker. 4) Turn on the gas to boiling the water. 5) Look at the thermometer and record the p.d and current each 5 C 6) Repeat this experiment. 7) Put all data into table. 8) Calculation the resistance and draw the graphs. The equation is: Resistance(R) = Potential different (p.d.) Current (I) Appliance list: Wires- Use these wires to link all appliances to complete the circuit. Power Supply- Use these supply the energy into circuit. Thermistor- I use this to change the resistance in the circuit. Voltmeter- Measuring the volt in the circuit across the thermistor. Ammeter- Measuring the current in the...
