Sensor resistance and physical conditions
What Sensor resistance and physical conditions means in Physics A-Level, as defined for OCR.
Definition of Sensor resistance and physical conditions
Check what you remember
Read the wording for your board, then hide it and explain Sensor resistance and physical conditions in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Warm or cool the thermistor, or change the light intensity on the LDR, and record how the sensor resistance and the output voltage change.
