Current, charge and voltage graphs
What Current, charge and voltage graphs means in Physics A-Level, as defined for OCR.
Definition of Current, charge and voltage graphs
Check what you remember
Read the wording for your board, then hide it and explain Current, charge and voltage graphs in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Graphs of charge, current and potential difference against time are exponential curves, and the area under a current-time graph gives charge.
