Specification P3.2g · Paper 1 (Foundation), Paper 3 (Higher)
A circuit element whose current is directly proportional to the potential difference across it, giving a straight-line graph through the origin.
Revise: Graphs of circuit elementsFor a linear circuit element, doubling the potential difference doubles the current, tripling it triples the current, and so on.
