Variable resistors and potentiometers
What Variable resistors and potentiometers means in Physics A-Level, as defined for AQA.
Definition of Variable resistors and potentiometers
Check what you remember
Read the wording for your board, then hide it and explain Variable resistors and potentiometers in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Replacing a fixed resistor with one of these allows the output p.d. to be varied continuously.
