Hi all,
If i have a charged plate of charge Q coulumbs, then what is the energy contained in it?
Is the energy independent of the way in which i managed to get a single plate of Q columbs charge? In the sense , suppose in the beginning there were two plates of charge +Q, -Q columbs and distance r apart, then i manage to apply mechanical energy against the electrostatic force of attraction between the plates and i separate it to large( say infinite) distance apart, then the mechanical energy spent will be--
Q^2/ 4pi(epsilon o)r
from law of conservation of energy this mechanical energy spent in seperating the plates must be stored as electric energy?? I am confused please help.
