Check what you remember
Read the wording for your board, then hide it and explain non-ohmic components in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Components such as lamps, diodes, thermistors and LDRs whose resistance is not constant but changes with the current through the component.
Components that change resistance with conditions, such as a filament lamp, a diode, an NTC thermistor and an LDR.
