Common capacitor values are determined by the capacitance of a capacitor, which for a parallel-plate capacitor like the one shown above is C=εA/d, where A is the area of the conducting plate (length x width), d is the separation between the plates, and ε is the permittivity of the medium between the plates.
So it stores the energy between the plates because of the attraction charges. The following circuit of a parallel plate capacitor is used to charge the capacitor. In this circuit, ‘C’ is the capacitor, the potential difference is ‘V’ and ‘K’ is the switch.
