Definition of Microscopic model of current
Check what you remember
Read the wording for your board, then hide it and explain Microscopic model of current in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Since I = Anev, at a fixed current a smaller n requires a larger drift velocity.
