Why the capacitor stores energy but not charge??

First of all, let's know what really storing anything means. To store something implies there should be presence of some extra amount of it in them. Like same storage of energy or charge in any system implies the net charge or energy in the system is not equal to zero.

Now let's consider a parallel plate capacitor in which the plate  connected to the positive terminal of a battery gets positive charge and induces same amount of negative charge on the another plate. So the total net charge...

A capacitor has a vacuum in the space between the conductor plates. If you double the charge on each conductor, what happens to the capacitance?

When charge is given to a capacitor thepotential difference across its plates rises. Asthe more and more charge is given, itspotential increases accordingly. If a charge Qis given to the capacitor so that its potentialrises through V, then it has been found thatcharge Q stored in it is directly proportional topotential difference V across the plates of thecapacitor. So,

or

Q = CV

where C is a proportionality constant, calledthe capacitance of the capacitor. Its valuedepends upon the shape and...
