What Graphical determination means in Physics A-Level, as defined for AQA.
Definition of Graphical determination
Check what you remember
Read the wording for your board, then hide it and explain Graphical determination in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Plotting ln V against time for discharge, where the gradient is −1/RC, so τ is the negative reciprocal of the gradient.
