Definition of Exponential fall during discharge
Check what you remember
Read the wording for your board, then hide it and explain Exponential fall during discharge in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
During discharge, the charge, current and potential difference all fall exponentially, and after one time constant each quantity has fallen to 1/e of its initial value, about 37%.
