2. 1(d)1 mark· Physics Q1 1(d)Using the information from the graph, comment on the relationship between the potential difference, (V), and the current (I).
3. 1(f)4 marks· Physics Q1 1(f)With reference to 1 (e), describe the procedure used to conduct the investigation.
4. 5(a)6 marks· Physics Q5 5(a)With the aid of a CLEARLY labelled circuit diagram, explain how the I – V characteristics of an unknown electrical component, X, may be determined.
5. 5(a)6 marks· Physics Q5 5(a)Describe an experiment that can be used to determine the resistance of a metallic conductor.
6. 5(a)6 marks· Physics Q5 5(a)With the aid of a diagram, describe an experiment that may be used to investigate the relationship between current, I, and potential difference, V, for a filament lamp. Sketch your expected result.
7. 5(a)(ii)2 marks· Physics Q5 5(a)(ii)Sketch the I-V graph for a functioning semi-conductor diode.
