Revise Edexcel GCSE Physics 10.2.5 LDRs and thermistors with the question bank and revision guides.
Describe how the resistance of a light-dependent resistor (LDR) varies with light intensity. • Describe how the resistance of a thermistor varies with change of temperature (negative temperature coefficient thermistors only). • Explain how the design and use of circuits can be used to explore the variation of resistance in the following devices a filament lamps b diodes c thermistors d LDRs.
