decreasing gradient
What decreasing gradient means in Physics GCSE, as defined for AQA.
Definition of decreasing gradient
Check what you remember
Read the wording for your board, then hide it and explain decreasing gradient in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
As the potential difference rises the filament heats, the resistance climbs, and the current no longer rises in proportion, so the curve bends over and its gradient falls.
