Introduction                  A capacitor consists of two conducting surfaces separated by a layer of an insulating medium called dielectric.The conducting surfaces may be in the form of either circular plates or be of spherical or cylindrical shape.                   The purpose of a capacitor is to store electrical energy by electrostatic stress in the dielectric. Capacitance of a Capacitor                   The property of a capacitor to store electricity/charge may be called its capacitance.The capacitance of a capacitor is defined as the amount of charge required to create a unit potential difference between its plates.                     If Q is the charge in coulomb to one of the two plated of a capacitor and V is the potential difference in volts between two plates then its capacitance...
