Current limiting
What Current limiting means in Physics A-Level, as defined for AQA.
Definition of Current limiting
Check what you remember
Read the wording for your board, then hide it and explain Current limiting in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The role of a series resistor, which drops the difference between the input voltage and the Zener voltage and limits the Zener current.
