Check what you remember
Read the wording for your board, then hide it and explain Exponential decay in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
On discharge, Q, V and I all fall exponentially from their initial values towards zero.
The count falls by a constant factor each round, producing an exponential curve.
