In a parallel plate capacitor of capacitance `C`, a metal sheet is inserted between the plates, parallel to them. If the thickness of the sheet is half of the separation between the plates. The capacitance will be

In a parallel plate capacitor of capacitance C, a metal sheet is inserted between the plates, parallel to them. The thickness of the sheet is half of the separation between the plates. The capacitance now becomes

For a parallel plate capacitor of capacitance C and plate separation d,

A parallel plate air capacitor has a capacitance C and the distance between the plates is d.A metallic plate of thickness d/3 is introduced between the plates of the capacitor. The new capacitance will be—

A parallel plate capacitor has a capacitance of 60 PF, when the plates of the capacitor and separated by a distance d. if a metal plate of thickness t=(d)/(3) is introduced between the plates, the capacitance will be

Two identical metal plates separated by a distance 'd' form parallel plate capacitor (air gap) of capacitance C. A metal sheet of thickness (d/2) and same dimensions is inserted between the plates ,so that the air gap is separated into two equals parts. The new capacity of the system will be:
