A-LevelPhysicsD.C. circuitsMay/June 2022Paper 1 Q331 Mark
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?
ALDR: increases, thermistor: increases
BLDR: increases, thermistor: decreases
CLDR: decreases, thermistor: increases
DLDR: decreases, thermistor: decreases
