Capacitance
What Capacitance means in Physics A-Level, as defined for OCR.
Definition of Capacitance
Check what you remember
Read the wording for your board, then hide it and explain Capacitance in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
The charge stored per unit potential difference, given by C = Q/V, where Q is the magnitude of charge on one plate and V is the potential difference across the capacitor.
