Can a single conductor be used as capacitor ?

[FAlonso]

Arright this appeared in my exam tomorrow and I was baffled by the question...Is there any way to store the charge in single conductor or the answer was "not possible" ?

Every conductor will need a little bit of charge on it to raise its potential. This is called self-apacitancehttp://en.wikipedia.org/wiki/Capacitance#Self-capacitance"
This is of course very small, and ignored most of the time.
