Light-dependent resistance
What Light-dependent resistance means in Combined Science GCSE, as defined for AQA.
Definition of Light-dependent resistance
Check what you remember
Read the wording for your board, then hide it and explain Light-dependent resistance in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The resistance of an LDR decreases as light intensity increases, because more charge carriers are released in the semiconductor material.
