Detailed explanation-1: -The capacitance is directly proportional to the surface areas of the plates, and is inversely proportional to the separation between the plates.
Detailed explanation-2: -If you double the area of a parallel-plate capacitor and reduce the distance between the plates by a factor of four, how is the capacitance affected? It will increase by a factor of two.
Detailed explanation-3: -Capacitance (C) is DIRECTLY PROPORTIONAL TO THE AREA OF THE TWO PLATES that directly overlap, the greater the overlapping area, the greater the capacitance. Capacitance is INVERSELY PROPORTIONAL TO THE DISTANCE BETWEEN THE PLATES. i.e. if the plates move apart, the capacitance reduces.
Detailed explanation-4: -The capacitance of a parallel plate capacitor depends on area of each plate, dielectric medium between the plates and distance between the plates.
