Sensing and switching applications
What Sensing and switching applications means in Physics A-Level, as defined for OCR.
Definition of Sensing and switching applications
Check what you remember
Read the wording for your board, then hide it and explain Sensing and switching applications in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Circuits in which a potential divider with a variable component is used, for example a light- or temperature-sensitive output p.d.
