Physics Coursework Filament Bulbs Aim: My aim is to find how changing the amount of voltage (potential difference) coming out of the power pack will affect the current while it is flowing through a filament bulb of 24W. Diagram: The power pack supplies a direct current (DC) to the circuit. The voltmeter is in parallel to measure the potential difference across the bulb and the ammeter is in series to measure the current flowing through the circuit. Method: 1. Get all the equipment and set it up as shown in the diagram. 2. Set power pack so that the voltage shows 10V on the voltmeter. 3. Record the number of amps that are flowing through the circuit by reading the ammeter. 4. Repeat steps 2 + 3 for 20, 30, 40 and 50 Volts. 5. Repeat the steps 2 through 4 two more times to get three sets of results. Make an average and this leaves you with a...
