Detailed explanation-1: -The capacitance of a parallel plate capacitor is directly proportional to the area of the plates and inversely proportional to the distance separating them, so if we could reduce the area between the primary and secondary and increase their separation, we would reduce the inter-winding capacitance.
Detailed explanation-2: -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-3: -Explanation: From the above discussion, it is clear that the capacitance of the capacitor is inversely proportional to the distance between the parallel plate capacitor. Hence, if the distance between the parallel plate capacitor is decreased then the capacitance of the capacitor will increase.
