9.	explain the effect of a metal sheet on the capacitance of capacitor when gap is completely filled by metal sheet
Answer» ghffgExplanation:Initially (before metal sheet INSERTED) the capacitance of a PARALLEL plate capacitor is C= dAϵ 0 where A be the area of plates and d be the separation between parallel plates.When a metal sheet inserted fully halfway between the parallel plates, the capacitance will be divided into two capacitors C 1 ,C 2 and they are in series.Thus, C 1 = (d/2)Aϵ 0 =2C and C 2 = (d/2)Aϵ 0 =2CThe equivalent capacitance , C 12 = C 1 +C 2 C 1 C 2 = 2C+2C2C×2C =C
