Read the wording for your board, then hide it and explain Filament lamp in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
A non-ohmic component in which increasing current raises the filament temperature, increasing lattice ion vibration and so increasing resistance.
A component that curves because increasing current heats the filament, raising resistance, so the gradient falls.
