Is it possible to charge a capacitor to any potential? Does it depend on the dielectric placed between them? Or, are there other factors affecting it?

So now if it is not a parallel plate capacitor..its a solid sphere with radius R...can it be limitlessly charged? – Prakash Regmi Jan 19 '13 at 13:51
No, at some point the electric field inside the insulator becomes large enoughy to make it a conductor, and the charge will dissipate. – jkej Jan 19 '13 at 14:46

Yes, you can charge capacitor to any potential if in a vaccum .

But placing a dielectric inside it defines its dielectric strength and breakdown voltage above which the covalent bonds in dielectric material breaks down to bring large amount of charge carriers and thus is starts acting as conductor and capacitance becomes infinite.

@PrakashRegmi do you like the answer... plz accept – ABC Mar 19 '13 at 10:45
