Physics (AS & A Level) · May / June 2022 · Paper 12 · Question 33

The intensity of light incident on a light-dependent resistor (LDR) is increased. The temperature of a thermistor is increased. In each case, the current in the component is maintained at a constant value. What happens to the potential difference across each component?

1. ALDR increases, thermistor increases
2. BLDR increases, thermistor decreases
3. CLDR decreases, thermistor increases
4. DLDR decreases, thermistor decreases
