Read the wording for your board, then hide it and explain Potential divider circuits in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Arrangements in which a thermistor produces a potential difference that varies with temperature, changing the share of the supply potential difference across each component.
A potential divider containing the sensor converts its resistance change into a voltage that can be sampled and digitised.
