If a potential difference V is applied between two conductors (or plates) placed closed together but insulated from each other, to produce charges +Q and -Q upon them, there is proportionality between the charge and the potential difference, which is expressed as:
Q ∝ V
or Q = C ᐧ V
where C is a constant called the Capacitance of the particular set of mutually insulated conductors, their distance apart and on the nature of the insulating material, between them. The insulating material is called the dielectric.
Such a construction of two conducting bodies (whether in the form of plates or spheres) placed close to each other but separated by an insulating material from each other is called a Capacitor or Condenser, and is used for storage of electrical energy.
From the above relation, the capacitance is given by:
C=QV
The charge Q is expressed in coulombs, the potential difference V in volts, then the capacitance C is expressed in farads.
