Paper 1
Revise: InputsA light-dependent resistor, or LDR, is a resistor whose resistance changes with light intensity. Resistance describes how strongly a component opposes electrical current. An LDR has higher resistance in darkness and lower resistance in bright light.
Name the component as well as the input: an LDR senses light, a thermistor senses temperature and an FSR senses applied force.
