Capacitors doubt..

Capacitors have huge capacity in terms of farads, compared to normal conductors. That is true. But having said that, because of their geometry, the maximum voltage that they can withstand is extremely small (before breakdown happens) compared to a normal conductor

So a capacitor may hold 10 uC of charge at 100V, and a normal conductor at 100,000 V. I don't get whats the big deal? :P.. so i don't like when people say capacitors can store a lot of charge..

WHat I think capacitors do is the following

anonymous · Answer

a) Capacitors will not lose charge if  i touch any one metallic plate (because of the inductive effect) unlike a normal conductor
hence these are the devices to store charge.. 

b) But i don't really get the potential part.. in capacitors we talk about potential difference between the plates (or with the ground)
but normal conductors we talk about potential (considering infinity to be zero potential).. so

can someone tell me something more fundamental idea of capacitor ? :P.. or is that it?
