Question text
35 A thermistor and a light-dependent resistor (LDR) are connected in series. A potential difference (p.d.) of 6.0V is applied across them as shown. +6.0 V thermistor LDR 0 V The thermistor has a resistance of 6000Ω in a cold room and 1000Ω in a warm room. The LDR has a resistance of 2000Ω in dim light and 500Ω in bright light. When is the p.d. across the LDR equal to 2.0V? A in a cold room with bright light B in a cold room with dim light C in a warm room with bright light D in a warm room with dim light

The thermistor has a resistance of 6000Ω in a cold room and 1000Ω in a warm room. The LDR
has a resistance of 2000Ω in dim light and 500Ω in bright light.
When is the p.d. across the LDR equal to 2.0V?
A in a cold room with bright light
B in a cold room with dim light
C in a warm room with bright light
D in a warm room with dim light
