1. OCR physics A definition....
Okay, a pretty simple question. For the definition of capacitance, do I need to state that it is the ratio of charged stored by a capacitor to the p.d across it or is the equation charge over p.d enough? I know they both say the same thing but I know how picky OCR can be!

Thanks

Just put both?

Capacitance is defined as the the ratio of charged stored by a capacitor to the p.d across it (optional given by <insert formula, which I'm guessing is just Q/V?>.

Just make sure that you do not give the equation on its own. If you use an equation as a definition, you must make it clear what each of the terms means (by which time, you may as well have given the written definition in the first place!).
4. Okay, thank you

Charge stored per unit potential difference will get you the marks

Got it! Thank you!
