Paper 1 H - SAMPLE SET 1 Q8
8) A student investigated how current varies with potential difference for two different lamps.
Her results are shown in Figure 10.
Her results are shown in Figure 10.
8.1) Complete the circuit diagram for the circuit that the student could have used to obtain the results shown in Figure 10. [3 marks]
8.2) Which lamp will be brighter at any potential difference?
Explain your answer.
Use Figure 10 to aid your explanation [2 marks]
8.3) Lamp B has the higher resistance at any potential difference.
Explain how Figure 10 shows this. [2 marks]
8.4) Both lamps behave like ohmic conductors through a range of values of potential difference.
Use Figure 10 to determine the range for these lamps.
Explain your answer. [3 marks]
