Can we calculate capacitance of an isloated meta plate?

[AnkurGarg]

i have done the capacitance of an isolated charged sphere (=4 pi E R).but can we find capacitance of an isolated ,infinite charged plate too??how?

The question is ill-defined. You can't have an infinite charged plate. At some distance, any plate will no longer appear infinite. A hypothetical infinitely plate has constant electric field lines, which means the voltage is infinite from an infinite distance away, so the capacitance is 0.

Ty brother!my teacher wasn't able to answer it!
