A circuit element whose current is not directly proportional to the potential difference across it, giving a curved current–potential difference graph.
Revise: Graphs of circuit elementsFor a non-linear circuit element, equal increases in potential difference do not produce equal increases in current. Its points form a curve rather than a single straight line through the origin.
