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,
Q V
or
Q = CV
where C is a proportionality constant, calledthe capacitance of the capacitor. Its valuedepends upon the shape and...
