Is it correct to say that the capacitance is inversely proportional to the area of the parallel plates?
True
False
Is there a limit to the amount of charge that capacitor can hold and why/why not?
Yes, as the ratio of charge to p.d. is fixed.
Yes, because the dielectric will breakdown in such a large field and charge will remain.
No, as capacitance can always increase as p.d. increases.
Yes, because the dielectric will breakdown in such a large field and charge will flow.

Coulombs
Farads
Hz
