Read the wording for your board, then hide it and explain Graph interpretation in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
A component is identified from the shape, symmetry and threshold of its graph, using the gradient or the ratio V/I to explain resistance changes.
Reading the labels carefully to identify which quantity is plotted on each axis before extracting values for V and I.
