Read the wording for your board, then hide it and explain Temperature dependence of resistance in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
A filament lamp's resistance rises as it heats with increasing current, whereas a thermistor's resistance falls as temperature rises.
Increasing temperature raises the lattice vibration and so increases resistance.
