Materials and critical limits
What Materials and critical limits means in Physics A-Level, as defined for AQA.
Definition of Materials and critical limits
Check what you remember
Read the wording for your board, then hide it and explain Materials and critical limits in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Critical temperature, critical current and critical field limit applications; above any critical value the material reverts to normal resistance.
