Capacitor question

'Can we go on adding charge indefinitely to a capacitor?' Is the question, the answer said 'the answer may refer to electrical breakdown of dielectric'. Can someone give an answer to this question please and explain it?
Thank you

Nah, you can't just keep charging a capacitor forever.
Guide lines:
-Every insulator has a limit to how much electric field it can take, it's called dielectric strength.
-If you go over that, the insulator breaks down and starts conducting.
-Then you get a sudden discharge between the plates.
-The capacitor can get fried for good.
-Basically, the insulator breaks down when the electric field gets too strong, and that's the limit.
