Experimental measurement of charge and p.d.
What Experimental measurement of charge and p.d. means in Physics A-Level, as defined for OCR.
Definition of Experimental measurement of charge and p.d.
Check what you remember
Read the wording for your board, then hide it and explain Experimental measurement of charge and p.d. in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Current and p.d. readings are recorded over time, and because charging current varies, charge Q is found from the area under an I-t graph, or a constant current circuit is used.
