The question as text
Fig. 6.1 shows a circuit diagram containing a battery, a light-dependent resistor (LDR) and a fixed resistor of resistance 240 Ω connected in series. 240 Ω LDR Fig. 6.1 There is a lamp near the circuit. Light from the lamp is incident on the LDR when the lamp is switched on. Fig. 6.2 shows the current−voltage graph for the LDR with the lamp switched on and with the lamp switched off. 0 0 0.02 0.04 0.06 0.08 0.10 1 2 3 4 5 6 7 voltage / V current / A 8 with lamp switched on with lamp switched off Fig. 6.2
