What Graphical analysis using gradients means in Physics A-Level, as defined for AQA.
Definition of Graphical analysis using gradients
Check what you remember
Read the wording for your board, then hide it and explain Graphical analysis using gradients in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
A graph of resistance R against length L is plotted, and since the gradient equals ρ/A, resistivity is found from gradient × A.
