3 Section AA resistor isanelectrical component that controlstheamount of current inacircuit.Two different types of resistors are shown in figure1. Figure 1 In this experiment you will investigate the resistance of a fixed resistor using thevoltmeter-ammeter method. You have been provided with 1. Two cells2. One fixed resistor labelledX3. Five colour banded resistors labelledAtoE4. Seven connecting leads with clips5. a voltmeter6. an ammeter7. a switch Figure 2 (a) Set up the apparatus as shown in figure 2 using resistorsXandA. (b) Close the switch. Record the ammeter reading. ammeter reading= _______________________ [1] _________________________________________________________________________________________________Canberra Secondary School Science Physics 5076/052020 Preliminary Examination Secondary 4 Express/ 5 Normal Academic

4 (c) Connect the voltmeter to the circuit as shown in figure3. Figure 3 (d) Record the voltmeter reading. voltmeter reading= _______________________ [1] (e) Calculate the power of the resistorX. power= _______________________ [1] (f) By replacing resistorAwith other colour banded resistors(BtoE), repeat step(d) for further sets of voltmeter readings, as well as the ammeter readings.Tabulate your readings below.
