(b) How does the resistance of a filament lamp change as the temperature of the filament changes? (1) (Total 7 marks) Q5. The drawing shows the circuit used to investigate how the current through a 5 ohm (Ω) resistor changes as the potential difference (voltage) across the resistor changes. (a) Draw, in the space below, a circuit diagram of this circuit. Use the correct symbols for each part of the circuit. (2)
